• What is the cause and solution for SAP error message GG197 - Only key fields are allowed ?

  The SAP error message GG197 "Only key fields are allowed" typically occurs in the context of data entry or data processing within SAP, particularly when dealing with key fields in a table or a data structure. This error indicates that the system expects only key fields to be entered or processed, and non-key fields are not permitted in that context.
  Cause:
  
  Incorrect Field Usage: The error usually arises when a user attempts to enter or manipulate data in a field that is not designated as a key field in the database table or structure.
  Data Model Constraints: The data model may have constraints that only allow key fields to be used in certain operations, such as updates or inserts.
  Configuration Issues: There may be configuration settings in the SAP system that restrict the use of non-key fields in specific transactions or processes.
  
  Solution:
  
  Check Field Definitions: Review the data structure or table definition to ensure that you are only using key fields in the operation that triggered the error.
  Correct Data Entry: If you are entering data manually, ensure that you are only inputting values into fields that are defined as key fields.
  Review Transaction Logic: If this error occurs during a transaction or program execution, check the logic to ensure that it adheres to the constraints of the data model.
  Consult Documentation: Refer to SAP documentation or help resources for the specific transaction or module you are working with to understand the requirements for key fields.
  Debugging: If you have access to debugging tools, you can trace the execution of the program to identify where the error is being triggered and adjust the logic accordingly.
