  The SAP error message /SAPAPO/RBA096 indicates that there is an attempt to create a substitution row in the SAP Advanced Planning and Optimization (APO) system, but a row with the same key already exists. This typically occurs in the context of product substitution, where one product can be substituted for another in planning scenarios.
  Cause:
  The error is caused by trying to create a substitution entry that duplicates an existing entry. The message provides details about the specific substitution row that is causing the conflict, indicated by the identifiers &1, &2, &3, and &4.

  Solution:
  To resolve this error, you can take the following steps:

  Review Data Input:
