Unable to add BAccountID from INTran to the grid in Modern UI

Hi ​@eduard83 
Since the dedicated field is declared in a non-primary DAC (INTran), you need to use the double-underscore approach. Therefore, add your field in the related .ts file extension as follows:

import { InventoryTranDetEnqResult } from "src/screens/IN/IN404000/IN404000";

import { PXFieldState } from "client-controls";

export interface InventoryTranDetEnqResult_MyProject extends InventoryTranDetEnqResult { }
export class InventoryTranDetEnqResult_MyProject {
	INTran__BAccountID: PXFieldState;
}

If I am correct and your screen is IN404000, it should work for you without any changes (except for replacing MyProject with your actual project name).

​@aleksandrsechin Thank you for your reply and explanation regarding the double-underscore approach.

I've already tried implementing the solution exactly as described (using INTran__BAccountID in the .ts file extension), but unfortunately, I didn't get the expected result—the field still doesn't appear in the table.

If there are any other ways to solve this problem, please let me know.

Thanks for your help.

1. What is the file path?
2. How do you build the screen?

Also, sometimes changes may not be reflected in the UI. You can check this topic and follow the steps described in the reply marked as Answer:

1. FrontendSources\screen\src\screens\IN\IN404000\extensions\IN404000_BZConsignment.ts
2. npm run build-dev --- --env screenIds=IN404000

      I will also attach my code below for clarity.

import { InventoryTranDetEnqResult } from "src/screens/IN/IN404000/IN404000";
import { PXFieldState } from "client-controls";
export interface InventoryTranDetEnqResult_BZConsignment extends InventoryTranDetEnqResult { }
export class InventoryTranDetEnqResult_BZConsignment {
    INTran__BAccountID: PXFieldState;
}

<template>
    <field after="#grid" name="INTran__BAccountID"></field>
</template> 

1. You don’t need to specify anything for a grid field in the .HTML file (only in the .ts file). So you can remove it entirely.
2. You should place your file into the development folder:
   FrontendSources\screen\src\development\screens\IN\IN404000\extensions
3. Use the following command to build the files placed in the development folder:
   npm run build-dev --- --env screenIds=IN404000 customFolder=development
4. Make sure to run this command from the FrontendSources\screen folder.

I’ve tried the code above, and it adds the field on my instance. So try the steps above first. If you still can’t resolve the issue, follow the steps described in the reply marked as Answer in the topic I mentioned in my previous reply.

​@aleksandrsechin I tried all these steps but unfortunately I couldn't solve the problem.

​@eduard83 I suggest that :
after completed steps suggested by ​@aleksandrsechin add those file extension in Customization Editor’s → Modern UI Files section like below snap.
(if not added/present) 
 

Try this also.

I hope it helps.

@aleksandrsechin, ​@Abhishek Niikam  The issue has been resolved. It was indeed related to the system — I deployed a new system using the same code, and everything is now working correctly.
Thank you for your help!
