• What is the cause and solution for SAP error message BUX_EEW025 - Only the first field can be a key field. ?

  The SAP error message BUX_EEW025 indicates that there is an issue with the definition of key fields in a data structure or table. Specifically, the error states that "Only the first field can be a key field," which means that in the context of the data structure you are working with, only the first field is allowed to be designated as a key field.
  Cause:
  This error typically arises in the following scenarios:
  
  Data Structure Definition: When defining a data structure or a table, multiple fields are incorrectly marked as key fields. In SAP, only the first field in a structure can be designated as a key field.
  Custom Development: If you are working with custom ABAP programs or enhancements, the error may occur due to incorrect definitions in the data dictionary (SE11) or in the ABAP code.
  Table Maintenance: When trying to maintain a table or structure in transaction codes like SE11 or SE16, if multiple fields are set as key fields, this error will be triggered.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Data Structure/Table Definition:
  
  Go to transaction SE11 (Data Dictionary).
  Enter the name of the table or structure that is causing the error.
  Check the field definitions and ensure that only the first field is marked as a key field. If there are multiple key fields, remove the key designation from all but the first field.
  
  
  
  Adjust ABAP Code:
  
  If the error is occurring in custom ABAP code, review the code to ensure that only the first field is being treated as a key field when defining internal tables or structures.
  
  
  
  Re-activate the Object:
  
  After making the necessary changes, activate the table or structure to ensure that the changes take effect.
  
  
  
  Testing:
  
  Test the changes by executing the transaction or program that was causing the error to confirm that the issue has been resolved.
