3774696 - Cannot Increase Assignment Reference Field Length

At Item level, the Assignment Reference Field (sourced from I_GLAccountLineItemSemTag) shows limited Length and you want to increase the displayed string Length. No specific Error Messages are shown.

SAP S/4HANA Cloud Public Edition

1. Open Ageing Report for Payables Analytical Report App.
2. Navigate to item-level Reporting where Assignment Reference Field is displayed.
3. Observe that longer values are truncated/limited and cannot be increased via Standard Settings.

• Field lengths for Standard Fields (for example, Assignment Reference in I_GLAccountLineItemSemTag) cannot be changed due to the Clean Core approach.
• Modification of Standard Data Elements/Domains is not supported.

For longer Assignment Reference needs:

1. Use the Custom Fields and Logic App to create a Custom Text Field with the required Length in a suitable Business Context (for example, Journal Entry Item).
2. Enable it for UIs/Reports.
3. Include it in Reporting.

For Analytics:

1. Build a Custom CDS View and/or Custom Analytical Query that includes the Custom Field alongside the standard Assignment Reference.
2. Publish the Query for end users.

Note: Store descriptive Content in existing long-text Fields (for example, Document Header or Item Text) and surface them in Reports.
