Develop Customizations

After upgrading from Acumatica 24R1 → 26R1, I’m now getting these errors when using POFixedDemand:The type name 'recordID' does not exist in the type 'POFixedDemand'The type name 'orderType' does not exist in the type 'POFixedDemand'The type name 'orderNbr' does not exist in the type 'POFixedDemand'The type name 'lineNbr' does not exist in the type 'POFixedDemand' I couldn’t find any mention of this in the developer release notes for 24R2 through 26R1.  Does anyone know if the class was extended or where there fields went? 

I have tried 20+ code variations and can’t seem to get this working.  Scoured here, stackoverflow and everything else I can find over the last month without a solution.  Some appeared to work in prior versions but not now. As the title says; would like these files attached to the email when it sends: Single code file I named POOrderEntry_Extension: using PX.Data;using PX.Objects.CR;using PX.Objects.PO;using System;using System.Collections;using System.Collections.Generic;using System.Linq;namespace Customizations{ [PXProtectedAccess] public abstract class POOrderEntry_Extension : PXGraphExtension<POOrderEntry> { [PXProtectedAccess] protected abstract IEnume

Hi everyone,I'm looking for a way to have the side ribbon (side panel) open by default when a user navigates to a specific screen — and ideally with a specific icon/tab pre-selected.Context:Specific ScreenID (e.g. a custom or standard screen) Specific side panel icon should be expanded automatically on load Goal: avoid the user having to click the icon every timeAny pointers, code samples, or references to the framework API would be greatly appreciated.Thanks!Raphael

Hi All.  I'm unable to add/delete Acumatica Customizations on 25R2 even though my user has the permissions and the access rights for the screen look correct. Am I missing something simple? 

Hi team,When attempting to change the Site Map setting from Classic UI to Modern UI, the Graph Type field disappears. This is working properly in the Dev site, but the issue is occurring only in the Production siteCould you please suggest? Below are the screenshots for reference.Dev site: Production site:   

I am working on a customization in Acumatica 2025 R2 using the Modern UI framework for the Sales Order screen (SO301000).I want to highlight the entire row in red whenever the CuryUnitPrice does not match my custom field UsrEDIPOPrice (which is defined in a SOLine extension).I have implemented a TypeScript file and an SCSS file. However, the row styling is not being applied. TypeScript Code (SO301000.ts) import { RowCssHandlerArgs, handleEvent, CustomEventType} from "client-controls";import "./SO301000_CYBEDIWebService.scss";export class SOOrderEntryExt { @handleEvent(CustomEventType.GetRowCss, { view: "Transactions" }) getTransactionsRowCss(args: RowCssHandlerArgs) { const row = args?.selector?.row; if (!row) return "";

Hi all,Happy Mothers Day!I needed a way to connect Claude to our Acumatica 2025 R2 instance right now, and the official Acumatica integration looks like it's still some time away. So I built one (entirely using Claude Code), ran it in production against our own ERP for a few weeks, and have now open-sourced it under Apache 2.0:Repo: https://github.com/hallboys/MCP4AcumaticaMCP4Acumatica is  a remote MCP (Model Context Protocol) server that runs on Cloudflare Workers. Each user logs in with their own Acumatica credentials — the server holds nothing centrally beyond an encrypted refresh token, and a user's normal Acumatica role governs what records they can read. Any MCP client (Claude.ai, Claude Desktop, Claude Code, ChatGPT) can talk to it.What's in the box (v0.31.1):38 read-on

I’m getting a build error in the UpdateExpirationDate() function:    public class KBCCProcessingCenterMaintExt : PXGraphExtension<CCProcessingCenterMaint>    {        [PXOverride]        public PXAction<CCProcessingCenter> updateExpirationDate;        public static bool IsActive() => PXAccess.FeatureInstalled<PX.Objects.CS.FeaturesSet.integratedCardProcessing>();        [PXUIField(DisplayName = "Update Expiration Dates", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]        [PXButton]        public virtual IEnumerable UpdateExpirationDate(PXAdapter adapter)        {            if (Base.ProcessingCenter.Current != null && Base.ProcessingCenter.Current.ProcessingTypeName == typeof(KBTokenizedProcessing).FullName)            {                throw new PXException(KBMessages.FeatNotSupported);            }            return Base.UpdateExpir

When upgrading from Acumatica 24R1 → 26R1, the CCProcessingCenterMaint.UpdateExpirationDate(PXAdapter adapter) is now missing in \App_Data\CodeRepository\PX.Objects\CA\CCProcessingCenterMaint.cs.  I was overriding this method but was still using the base.  Was this method moved somewhere else?

I’m planning to migrate custom screens to Modern UI in 2025R2 and want to confirm:Has the Modern UI architecture been finalized in 2025R2? Are there no major disruptive changes planned for 2026R1/R2? If I complete all Modern UI customizations in 2025R2, can I upgrade directly to 2026R2 later without needing to redo these customizations in 2026R1 first?

I’m now getting this compilation error:'SOShipmentEntry' does not contain a definition for 'OrderList' and no accessible extension method 'OrderList' accepting a first argument of type 'SOShipmentEntry' could be found (are you missing a using directive or an assembly reference?)So I noticed that it was moved to SOOrderExtension in 2025R2.  However, the graph for this is incompatible with SOShipmentEntry:PX.Objects.SO.GraphExtensions.SOShipmentEntryExt.SOOrderExtension docgraph = PXGraph.CreateInstance<PX.Objects.SO.GraphExtensions.SOShipmentEntryExt.SOOrderExtension>();This is the compilation error that I get:The type 'PX.Objects.SO.GraphExtensions.SOShipmentEntryExt.SOOrderExtension' cannot be used as type parameter 'Graph' in the generic type or method 'PXGraph.CreateInstance<Graph>()'. There is no implicit reference conversion from 'PX.Objects.SO.GraphExtensions.SOShipmentEntryExt.SOOrderExtension' to 'PX.Data.PXGraph'.

How do i have to use PX.Data.XLSXReader to read a specific sheet of the XLSX-File?

Using an instance of 25.200.0020 (clean install), I need to customise screen AP303000 to add some fields (specifically AddressLine3), but on opening the Modern UI Editor from the Customization Project Editor for that screen, I get the error message: In HTML extension “C:\..\FrontendSources\screen\src\screens\AP303000\extensions\AP303000_PersonalDataPrivacy.html” for screen ‘AP303000’ child node ‘QP-FIELDSET’ has AFTER attribute with ‘#groupAccountAddress’ but screen HTML doesn’t contain any elements that satisfies such querySelector.I can work around this locally by renaming the source files AP303000_PersonalDataPrivacy.html and .ts (adding a suffix of .x). But I’m concerned that the same hack won’t be possible in production. 

Hi Team,I am working on adding a custom tab to the Project Task screen in the modern UI. However, I am encountering an issue where the tab does not display correctly.When I click the arrow icon available on the screen, the custom tab appears as "undefined" instead of showing the expected content or label.I have already reviewed the related files and configuration, but I am unable to identify the root cause of the issue.Expected Behavior:The custom tab should display with the correct label and content when selected.Actual Behavior:The tab shows "undefined" when clicked.Could anyone please guide me on what might be causing this issue or how to resolve it?Thanks in advance. HTLM Code  <qp-tab id="tabSubTasks" caption="SubTasks">      <qp-template id="tabSubTasks_TaskProperties_CstFormView2_div0" qp-collapsible="">        <qp-fields

When doing stock take, I want to be able to see stock item’s Alternate ID, specifically for ‘OEM Part Numbers’ - I want the Alternate ID on Prepare Physical Count review, Physical Inventory Count and Physical Inventory Review screen. I note they are not a generic inquiry screens and thought this is possible via customizations? 

Has updating system DLLs used by Acumatica and adding binding redirects been a problem for anyone?   I’m considering updating and adding the following:<dependentAssembly>  <assemblyIdentity name="Microsoft.Bcl.Memory" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />  <bindingRedirect oldVersion="0.0.0.0-10.0.0.0" newVersion="10.0.0.0" /></dependentAssembly><dependentAssembly>  <assemblyIdentity name="System.ClientModel" publicKeyToken="92742159e12e44c8"culture="neutral" />  <bindingRedirect oldVersion="0.0.0.0-1.4.0.0" newVersion="1.4.0.0" /></dependentAssembly><dependentAssembly>  <assemblyIdentity name="Microsoft.Extensions.AI.Abstractions" publicKeyToken="31bf3856ad364e35" culture="neutral" />  <bindingRedirect oldVersion="0.0.0.0-10.0.0.0" newVersion="10.0.0.0" /></dependentAssembly><dependentAssembly>

I have created a 25R2 Modern UI instance, added all 25R2-related dependencies into the automation framework, and created wrappers for CS201010 using 25R2 (ClassGenerator.exe.config). However, when I run the automation test script, the automation report shows errors, such as the “Add” button not being present, even though it is visible in the UI. 

I have an issue where clicking grid toolbar buttons (such as Add, Reload, or Delete) causes the page to scroll back to the top.On my screen, I have several panels located toward the bottom, each containing grids. When I interact with the toolbar buttons in these lower grids, the page unexpectedly jumps to the top instead of staying in place.Has anyone encountered this behavior or knows how to prevent the page from scrolling to the top?

Why are some DLLs that are referenced by a DLL I’m creating not on the list when I attempt to add them to the customization?  Others are there.  System.ClientModel, for instance, doesn’t appear in the add files list, yet Markdig does.  How does Acumatica decide which DLLs are in the Add Files list?DLL Solution: 

Hi Everyone!I am in the process of pulling apart the Related Items functionality and putting it back together to try to understand some issues that we are having with the Related Items popup on sales orders.The first issue is that not all tabs are displaying on the Add Related Items popup on classic UI, but they do show up on Modern UI. However, even then, the data does not populate correctly. This may be due to a volume of data issue, which we should be able to fix with a custom override to force a refresh of the query cache.As a note, we anticipate

I’ve created a very simple customization that simply attempts to populate a richtext box on a button click.  The box renders as a white area without the richtext box header, which I’m fine with.I’m getting a “undefined: Cannot read properties of undefined (reading 'getvalue')” message as a popup.  Others have had this in the past (question from two years ago is the same).  I’ve tried the suggested solution without success.Here is my current ASPX code for the control...      <pxa:PXRichTextEdit AllowImageEditor="False" AllowInsertParameter="False" AllowLinkEditor="False" AllowNull="True" Required="False" ID="CstPXTextEdit5" runat="server"             Style="z-index: 113; border-width: 0px;"            AllowAttached="true" AllowSearch="true" AllowLoadTemplate="false" AllowSourceMode="true"            DataField="Answer" Width="800" Height="900">            <ContentStyle BorderStyle="None" ></ContentStyle>

Is there a way to display formatted markdown text in Acumatica?  I can get html or markdown results from the API that I’m calling, but don’t know how to display the results to the user.  

 Maybe this question is very simple, but I can’t find an answer about it.I know that if I write an event like this and do not call baseMethod inside the body, the base method code will not execute. If I want the base code to run, I must explicitly call it. This part is clear to me.​​​​​​​protected void _(Events.RowSelected<ARInvoice> e, PXRowSelected baseMethod) { }When I write the event like this, I tested that the base methods are called automatically:protected void _(Events.RowSelected<ARInvoice> e) { }But I do not understand why this happens. I tried to find something in the documentation.In the 2026 R1 Developer Guide, I found information that seems to contradict what I observed during testing. In T210, I found events wri

I am trying to customize a Branch lookup in Acumatica so that it only shows branches belonging to the currently logged-in user's organization.When a user opens the Branch selector, it should display only branches that belong to the same organization as the current branch.The following SQL query returns the correct result:SELECT *FROM BranchINNER JOIN Branch AS Br ON Br.OrganizationID = Branch.OrganizationIDWHERE Br.BranchID = 22;Here, 22 represents the current logged-in branch (AccessInfo.BranchID in Acumatica).I tried to convert the same logic into BQL, but the result returns duplicate records instead of the expected filtered list.  Below are some of the approaches I tried: I also tried severa
