• What is the cause and solution for SAP error message /CFG/DB075 - Key field &1 of record &2 cannot be modified ?

  The SAP error message /CFG/DB075 Key field &1 of record &2 cannot be modified typically indicates that you are trying to modify a key field in a database record that is not allowed. Key fields are essential for uniquely identifying records in a database table, and modifying them can lead to data integrity issues.
  Cause:
  
  Key Field Modification: The error occurs when an attempt is made to change a key field of a record that is already stored in the database. Key fields are usually defined in the database schema and are not meant to be altered once a record is created.
  Data Integrity Constraints: The system enforces data integrity rules that prevent changes to key fields to maintain the uniqueness and consistency of the data.
  Incorrect Logic in Custom Code: If there is custom code (e.g., ABAP programs, user exits, BAdIs) that attempts to modify key fields, it can trigger this error.
  
  Solution:
  
  Avoid Modifying Key Fields: Review the logic of your program or transaction to ensure that you are not attempting to modify key fields. If you need to change a key field, you may need to delete the existing record and create a new one with the desired key value.
  Check Custom Code: If you have custom developments, check for any code that might be trying to modify key fields. Adjust the logic to prevent such modifications.
  Use Appropriate Transactions: If you are using standard SAP transactions, ensure that you are following the correct procedures for updating records. Some transactions may have specific rules regarding which fields can be modified.
  Consult Documentation: Refer to SAP documentation or help resources for the specific module you are working with to understand the constraints related to key fields.
  
  Related Information:
  
  Key Fields: In SAP, key fields are defined in the data dictionary (SE11) and are crucial for the identification of records in database tables.
