• What is the cause and solution for SAP error message SABP_KEY_REDUNDANCY016 - Check whether both keys are necessary ?

  The SAP error message SABP_KEY_REDUNDANCY016 indicates that there is a redundancy in the key fields defined for a particular data structure or table. This typically occurs when two or more key fields are defined in such a way that they do not provide unique identification for the records, leading to potential conflicts or ambiguities in data retrieval.

  Data Model Changes: Changes in the data model or business requirements may render certain key fields unnecessary.
  
  
  Solution:
  
  Review Key Definitions: Check the definitions of the key fields in the relevant data structure or table. Identify if both keys are indeed necessary for
