  The SAP error message MX502 typically indicates that there is an issue with the configuration of a multiplex table in the context of SAP's data modeling or database management. Specifically, the error suggests that a certain table is not recognized as a dependent table of a multiplex table, which can lead to issues in data retrieval or processing.
  Cause:
  
  Incorrect Table Configuration: The table in question may not be properly configured as a dependent table of the multiplex table. This can happen if the relationships between tables are not correctly defined in the data model.
  Missing Dependencies: The table may not have the necessary foreign key relationships or dependencies defined that would allow it to be recognized as part of the multiplex structure.

  Check Table Configuration: Review the configuration of the table in the data model. Ensure that it is correctly defined as a dependent table of the multiplex table.
