• What is the cause and solution for SAP error message C_027 - &: Only SELTABLE-OPT 'EQ' condition is allowed ?

  The SAP error message C_027 &: "Only SELTABLE-OPT 'EQ' condition is allowed" typically occurs in the context of ABAP programming, particularly when dealing with selection options in database queries. This error indicates that the selection table option being used is not valid for the specific context in which it is being applied.
  Cause:
  The error arises when a selection option (like a WHERE clause in a database query) is using a condition that is not allowed. In this case, the only valid condition for the selection table option is 'EQ' (equals). This means that the system expects a direct equality check, and any other condition (like 'NE', 'GT', 'LT', etc.) is not permitted.
  Solution:
  To resolve this error, you should:
  
  
  Check the Selection Options: Review the code where the selection options are defined. Ensure that you are only using the 'EQ' condition for the relevant fields.
  
  
  Modify the Code: If you find that other conditions are being used, modify the code to replace them with 'EQ'. For example, if you have something like:
  SELECT * FROM your_table WHERE your_field NE 'value'.
  Change it to:
  SELECT * FROM your_table WHERE your_field = 'value'.
  
  
  Review Documentation: If you are unsure about the allowed conditions for a specific selection option, refer to the SAP documentation or the ABAP programming guidelines for more details.
  
  
  Testing: After making the necessary changes, test the program to ensure that the error is resolved and that the logic of your query still meets the intended requirements.
  
  
  Related Information:
  
  ABAP Programming: Understanding how selection options work in ABAP is crucial. Familiarize yourself with the syntax and rules governing database queries in ABAP.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message, as there may be known issues or additional guidance provided by SAP.
  Debugging: Use the ABAP debugger to step through the code and identify where the invalid condition is being applied, which can help in pinpointing the exact location of the error.
  
  By following these steps, you should be able to resolve the C_027 error and ensure that your ABAP code functions correctly.
