• What is the cause and solution for SAP error message SWF_RLS_001120 - Operator '&1' cannot compare one-line and multiline values ?

  The SAP error message SWF_RLS_001120, which states "Operator '&1' cannot compare one-line and multiline values," typically occurs in the context of workflow rules or conditions where there is an attempt to compare values of different types—specifically, a single-line value with a multi-line value.
  Cause:
  This error arises when a comparison operation is attempted between a single-line string (a value that is expected to be on one line) and a multi-line string (a value that can contain line breaks). The comparison operators (like =, <>, <, >, etc.) cannot handle this mismatch in data types, leading to the error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Types: Review the variables or fields involved in the comparison. Ensure that both values being compared are of the same type (either both should be single-line or both should be multi-line).
  
  
  Convert Values: If you need to compare a single-line value with a multi-line value, consider converting the multi-line value to a single-line format. This can be done by:
  
  Removing line breaks from the multi-line string.
  Concatenating the lines into a single string.
  
  
  
  Modify the Workflow Logic: If the logic of your workflow allows, adjust the conditions to ensure that comparisons are made between compatible types.
  
  
  Use Functions: If applicable, use SAP functions or methods that can handle multi-line strings appropriately, ensuring that the comparison logic is valid.
  
  
  Testing: After making changes, test the workflow to ensure that the error is resolved and that the logic behaves as expected.
  
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or specific documentation related to the workflow engine you are using for more details on data types and comparison operations.
  Debugging: Use debugging tools within SAP to trace the values being compared and identify where the mismatch occurs.
  Community Forums: Check SAP community forums or support channels for similar issues and solutions shared by other users.
  
  By following these steps, you should be able to resolve the SWF_RLS_001120 error and ensure that your workflow operates correctly.
