• What is the cause and solution for SAP error message DDLS426 - Return parameter & of type NUMC can have a maximum length of 69 ?

  The SAP error message DDLS426 indicates that there is an issue with a return parameter defined in a function module or method. Specifically, it states that a parameter of type NUMC (numeric character) can have a maximum length of 69 characters. This error typically arises when the length of the NUMC parameter exceeds the allowed limit.
  Cause:
  
  Parameter Length Exceeded: The return parameter defined in the function module or method is set to a length greater than 69 characters. In SAP, NUMC fields are used to store numeric values as character strings, and they have a maximum length restriction.
  Data Dictionary Definition: The data dictionary definition for the NUMC type may have been incorrectly set, or the function module/method may have been designed to return a longer numeric string than is permissible.
  
  Solution:
  
  
  Check Parameter Definition: Review the definition of the return parameter in the function module or method. Ensure that the length of the NUMC parameter does not exceed 69 characters.
  
  If you are using a custom function module, you can adjust the length of the parameter in the function module definition.
  If the function module is standard, you may need to check if you are using it correctly or if there is an alternative approach.
  
  
  
  Modify the Length: If you have control over the function module or method, modify the length of the return parameter to be within the allowed limit (69 characters or less).
  
  
  Data Handling: If the data being returned is inherently longer than 69 characters, consider alternative approaches:
  
  Split the data into multiple return parameters.
  Use a different data type that can accommodate longer strings, such as CHAR or STRING, if appropriate for your use case.
  
  
  
  Testing: After making changes, test the function module or method to ensure that it works correctly and that the error message no longer appears.
  
  
  Related Information:
  
  NUMC Data Type: In SAP, NUMC is a data type used for storing numeric values as character strings. It is often used for fields that require numeric input but may also include leading zeros or other formatting.
  Function Module Documentation: If you are using a standard SAP function module, refer to the SAP documentation or the function module's help text for guidance on its parameters and usage.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional context.
  
  By following these steps, you should be able to resolve the DDLS426 error and ensure that your return parameters are correctly defined and used within the constraints of SAP's data types.
