• What is the cause and solution for SAP error message FRMLAPI104 - Update or deletion is not possible; foreign key field was changed ?

  The SAP error message FRMLAPI104 indicates that an update or deletion operation cannot be performed because a foreign key field has been changed. This typically occurs in the context of database operations where referential integrity is enforced. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Foreign Key Constraint: The error arises when you attempt to update or delete a record that is linked to another record through a foreign key relationship. If the foreign key field in the child table is modified, it can violate the integrity of the relationship with the parent table.
  Data Integrity Rules: SAP enforces data integrity rules to ensure that relationships between tables remain consistent. Changing a foreign key field can lead to orphaned records or inconsistencies in the database.
  
  Solution:
  
  Check Foreign Key Relationships: Review the foreign key relationships in your database schema. Ensure that any changes you are trying to make do not violate these relationships.
  Revert Changes: If you have changed a foreign key field, consider reverting it to its original value before attempting the update or deletion again.
  Update Related Records: If you need to change the foreign key field, ensure that all related records in the child table are updated accordingly to maintain referential integrity.
  Use Proper Transaction Management: If you are performing multiple updates or deletions, ensure that they are part of a single transaction to maintain consistency.
  Consult Documentation: Refer to SAP documentation or your organization's guidelines for handling foreign key constraints and data integrity issues.
  
  Related Information:
  
  Database Design: Understanding how foreign keys work in relational databases is crucial. Foreign keys are used to link tables and enforce relationships.
  SAP Modules: This error can occur in various SAP modules, especially those involving data entry or batch processing (e.g., MM, SD, FI).
  Debugging: If you are a developer or administrator, you may want to enable debugging or logging to capture more details about the operation that triggered the error.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions to common problems.
  
  Conclusion:
  To resolve the FRMLAPI104 error, you need to ensure that any changes to foreign key fields do not violate existing relationships in the database. By carefully managing your data updates and adhering to referential integrity rules, you can avoid this error in SAP.
