3679381 - Inconsistency in Custom Field Display Across AP and GL Applications

• A custom field of type URL (YY1_URL) was created using the Custom Fields application.

• The field is enabled for UI usage and appears in both applications:

  • Display Line Items in General Ledger

  • Manage Supplier Line Items

• The field correctly displays URL values in the Display Line Items in General Ledger app.

• In the Manage Supplier Line Items app, the field is visible but appears empty (no data).

SAP S/4HANA Cloud Public Edition

1. Create a custom field of type URL with the business context Journal Entry Item (FINS_JOURNAL_ENTRY_ITEM) using the Custom Fields app.

2. Enable the field for UI usage and relevant apps.

3. Implement substitution logic in the BAdI FIN_ACDOC_EXT_SUBSTITUTION to populate the field value.

4. Post a journal entry and verify the field values:

   1. In the Display Line Items in General Ledger app -> field value is displayed.

   2. In the Manage Supplier Line Items app -> field appears empty.

• The BAdI FIN_ACDOC_EXT_SUBSTITUTION updates data only in the ACDOCA table.

• The Display Line Items in General Ledger app reads data from ACDOCA, so the field value is displayed correctly.

• The Manage Supplier Line Items app reads data from BSEG, where the custom field value is not updated.

• Hence, the field appears empty in apps based on BSEG, even though it is visible in the UI.

• Implement the substitution logic using the BAdI FIN_ACDOC_SUBSTITUTION instead of FIN_ACDOC_EXT_SUBSTITUTION.

• This BAdI supports substitution at the item level and ensures data is updated in both ACDOCA and BSEG tables during journal entry posting.

• Steps to resolve:

  1. Create or open an implementation under FIN_ACDOC_SUBSTITUTION.

  2. Move the existing substitution logic from FIN_ACDOC_EXT_SUBSTITUTION to FIN_ACDOC_SUBSTITUTION.

  3. Test posting a journal entry and verify the URL field now appears populated in both applications.
