• What is the cause and solution for SAP error message STOBJ147 - Association &-&: Comparison value has forbidden type & ?

  The SAP error message STOBJ147 indicates that there is a type mismatch in a comparison operation within your ABAP code or configuration. Specifically, the message states that the comparison value has a "forbidden type," which means that the data types being compared are not compatible.
  Cause:
  
  Type Mismatch: The most common cause of this error is that the data types of the variables or fields being compared are not compatible. For example, you might be trying to compare a character field with a numeric field.
  Domain Restrictions: The comparison might involve fields that have specific domain restrictions that prevent certain types of comparisons.
  Incorrect Data Assignment: There may be an issue with how data is being assigned or initialized, leading to a type that is not expected.
  
  Solution:
  
  Check Data Types: Review the data types of the variables or fields involved in the comparison. Ensure that they are compatible. You can use the ABAP Data Dictionary (SE11) to check the definitions of the fields.
  Type Conversion: If necessary, perform explicit type conversion using ABAP functions like CONVERT or CAST to ensure that the types match before the comparison.
  Debugging: Use the ABAP debugger to step through the code and inspect the values and types of the variables at runtime. This can help identify where the type mismatch occurs.
  Review Domain Definitions: If the fields are based on domains, check the domain definitions to ensure that they allow the types you are trying to compare.
  Code Review: If the error occurs in custom code, review the logic to ensure that comparisons are being made between compatible types.
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the different ABAP data types (e.g., CHAR, NUMC, INT, etc.) and their compatibility.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Documentation: Refer to the official SAP documentation for more details on data types and comparison operations in ABAP.
