Symptom
You would like to know the relevance of "ISD Inv No" field in ISD redistribution?
Environment
SAP S/4HANA Cloud Public Edition
Reproducing the Issue
- Open the Re-distribute and Create ISD Invoices app.
- Enter Company Code, Fiscal Year, ISD Business Place, and Document Number (for example, 1900001817).
- Choose Post Invoice Distribution.
- Select Execute and Post.
- Observe that the ISD Reference Number field is blank.
Cause
- The ISD Reference Number (ISD Inv No) is a reference field that stores the distribution number of the original invoice’s accounting document when a credit memo is created and distributed for that original invoice.
- The field is not populated during “Invoice Distribution” for invoices and remains blank until a credit memo distribution is posted.
Resolution
Note that this is standard system behavior: the ISD Reference Number field is populated only during credit memo processing and posting.
