  The SAP error message REP_EAPS_MSG155, which states that "Table fields '&1' and '&2' are incompatible," typically occurs in the context of data processing or reporting, particularly when there is an attempt to join or compare fields from different tables that do not have compatible data types or structures.
  Cause:
  
  Data Type Mismatch: The fields being compared or joined have different data types (e.g., one is a character field while the other is a numeric field).
  Field Length Differences: The lengths of the fields may differ, which can lead to incompatibility.
  Domain or Data Element Issues: The fields may be based on different domains or data elements that impose different constraints or formats.

  Data Conversion: If necessary, use conversion functions (like CAST or CONVERT) to explicitly convert one field to the type of the other before comparison.
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or ABAP team for specific guidance related to the tables and fields involved.
