/CFG/DSY_DS052 - Details

• The SAP error message /CFG/DSY_DS052 Check table &1 has more than one key column (neglecting client) typically occurs in the context of Data Services or when working with Data Quality and Data Integration tools in SAP. This error indicates that the check table specified has multiple key columns, which is not allowed in certain contexts, particularly when defining a check table for a data quality check or a data flow.
  
  Cause:
  
  Multiple Key Columns: The check table you are trying to use has more than one key column. In SAP, certain operations or configurations expect a check table to have a single key column to ensure uniqueness and proper referencing.
  Client Handling: The error message specifies "neglecting client," which means that the system is ignoring the client field (MANDT) when checking for key columns. Therefore, if the check table has multiple key columns excluding the client field, it will trigger this error.
