• What is the cause and solution for SAP error message /CFG/DSY_DS052 - Check table &1 has more than one key column (neglecting client) ?

  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.
  
  Solution:
  
  Review the Check Table: Check the definition of the table specified in the error message. You can do this by using transaction SE11 (Data Dictionary) to view the structure of the table.
  Modify the Table Structure: If possible, modify the check table to ensure it has only one key column. This may involve:
  
  Creating a new table with a single key column.
  Adjusting the existing table to remove additional key columns if they are not necessary.
  
  
  Use a Different Table: If modifying the existing check table is not feasible, consider using a different check table that meets the requirement of having a single key column.
  Consult Documentation: Review SAP documentation or help resources related to the specific Data Services or Data Quality tool you are using to understand the requirements for check tables.
  
  Related Information:
  
  Data Services: If you are using SAP Data Services, ensure that your data flows and transformations are correctly configured to use check tables that comply with the key column requirements.
  Data Quality: In the context of data quality checks, ensure that the tables you are referencing for validation or cleansing have the appropriate structure.
  SAP Notes: Check for any relevant SAP Notes that might address this issue or provide additional guidance on handling check tables in your specific version of SAP.
