Payables Linked to Service Orders

HI ​@MFarnsworth10 ,

Can you check below,

The Acumatica Field Service module already provides this infrastructure. No custom development is needed — only configuration and UI exposure.
Technical Details
Existing Components:

Key Fields on AP Bill Lines (via FSxAPTran):
SrvOrdType          — string(4), FK to FSSrvOrdType
ServiceOrderRefNbr  — string(15), FK to FSServiceOrder
ServiceOrderLineNbr — int, FK to FSSODet.LineNbr
AppointmentRefNbr   — string(20), optional appointment link
RelatedDocNoteID    — Guid, NoteID of linked service order
Implementation Steps
1. Verify Feature Activation
   - Navigate to Enable/Disable Features (CS100000)
   - Confirm Service Management module is active
   - Confirm Field Service in AP Bills (or equivalent sub-feature) is enabled
2. Expose Fields on AP Bill Screen (AP301000)
   - Open the AP Bill screen in the Customization Project Editor
   - On the Document Details grid, add the following columns if not already visible:
     - FSxAPTran.SrvOrdType (label: "Service Order Type")
     - FSxAPTran.ServiceOrderRefNbr (label: "Service Order Nbr.")
   - Publish the customization
3. Validate Data Flow
   - Create an AP Bill with a line item
   - Select a Service Order Type and Ref Nbr on the line
   - Save and release the bill
   - Open the referenced Service Order and confirm a new detail line appears with LinkedEntityType = APBill
   - Verify cost amounts match
4. Permissions / Access Rights
   - Ensure relevant AP Clerk and Field Service roles have access to the FSxAPTran fields
   - If using restriction groups, confirm service order visibility for AP users

Hope above helps!
