  The SAP error message SDDL_PARSER_MSG329 indicates that there is an issue with the column prefixes used in an ON condition of a SQL statement or a similar query in SAP. Specifically, it states that only the prefixes "&1" and "&2" are allowed, which typically refer to the two tables being joined in the query.
  Cause:
  This error usually occurs when:
  
  You are trying to use a column prefix that is not recognized or allowed in the context of the ON condition.

  FROM Table1 AS T1
  JOIN Table2 AS T2
  ON T1.column_name = T2.column_name
  
  
  Review Documentation: If you are unsure about the allowed prefixes or the correct syntax, refer to the SAP documentation or the specific module documentation related to the query you are working with.
