CUMTX257 - Details

• The SAP error message CUMTX257, which states "Table accesses for inference of values defined ambiguously," typically occurs in the context of SAP's Advanced Business Application Programming (ABAP) or when working with the SAP Business Rules Framework (BRF+). This error indicates that there is an ambiguity in the way values are being inferred from the database tables, which can lead to confusion in the logic of the application.
  
  Cause:
  
  Ambiguous Definitions: The error often arises when there are multiple entries in the database that could satisfy a condition, but the system cannot determine which one to use. This can happen if the data model is not well-defined or if there are overlapping conditions in the rules.
  Incorrect Configuration: If the configuration of the rules or the data model is not set up correctly, it can lead to situations where the system cannot infer a single, unambiguous value.
  Data Integrity Issues: Duplicate or inconsistent data entries
