• What is the cause and solution for SAP error message SWF_BND_001090 - Data types '&1' and '&2' are not compatible ?

  The SAP error message SWF_BND_001090 indicates that there is a type mismatch between two data types in a workflow binding. This typically occurs when you are trying to bind data from one element to another, and the data types of the source and target do not match.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that the data types of the source and target elements are not compatible. For example, you might be trying to bind a string to an integer or a structure to a simple data type.
  Incorrect Mapping: The mapping of workflow variables or attributes may not be set up correctly, leading to incompatible types.
  Changes in Data Types: If there have been recent changes in the data model or the workflow definition, it may lead to inconsistencies in the expected data types.
  
  Solution:
  
  Check Data Types: Review the data types of both the source and target elements in the workflow. Ensure that they are compatible. You can do this by checking the definitions in the workflow editor or the relevant data dictionary.
  Adjust Bindings: If you find that the data types are indeed incompatible, you will need to adjust the bindings. This may involve changing the data type of one of the elements or using a conversion function to ensure compatibility.
  Use Conversion Functions: If necessary, use conversion functions (like CONVERT_TO_STRING, CONVERT_TO_INTEGER, etc.) to convert the data from one type to another before binding.
  Test the Workflow: After making changes, test the workflow to ensure that the error is resolved and that the data is being processed correctly.
  
  Related Information:
