• What is the cause and solution for SAP error message AD309 - Table & (no key field points to domain &) ?

  The SAP error message AD309 indicates that there is an issue with a table definition in the Data Dictionary (DDIC).

This can occur when a table is defined without a primary key or when the key fields do not correspond to the expected domain.
  Cause:
  
  Missing Key Fields: The table is defined without any key fields, which is a requirement for database tables in SAP.
  Incorrect Domain Assignment: The key fields that are defined do not match the domain specified in the error message.
  Table Definition Issues: There may be inconsistencies or errors in the table definition that prevent it from being recognized correctly.
  
  Solution:
