• What is the cause and solution for SAP error message SALV_BS_MSG307 - Comparison operators must be at the start in a filter condition ?

  The SAP error message SALV_BS_MSG307 indicates that there is an issue with the filter condition in an ALV (ABAP List Viewer) report. Specifically, the error states that comparison operators must be at the start of a filter condition. This typically occurs when you are trying to apply a filter to an ALV grid or list, and the syntax of the filter condition is not correct.
  Cause:
  The error is caused by the way the filter condition is defined. In ALV, when you specify a filter condition, it must start with a comparison operator (like =, <>, <, >, <=, >=, etc.). If the filter condition does not start with a valid comparison operator, the system will throw this error.
  Solution:
  To resolve this error, you should check the filter condition you are applying and ensure that it starts with a valid comparison operator. Here are the steps to troubleshoot and fix the issue:
  
  
  Review the Filter Condition: Look at the code where you are setting the filter condition. Ensure that the condition starts with a comparison operator.
  Example of a correct filter condition:
  filter_condition = 'FIELD_NAME = ''VALUE'''
  Example of an incorrect filter condition:
  filter_condition = 'VALUE = FIELD_NAME'
  
  
  Modify the Condition: If you find that the condition does not start with a comparison operator, modify it accordingly.
  
  
  Test the Changes: After making the necessary changes, test the ALV report again to ensure that the error is resolved.
