  The SAP error message /SMB/CHECK_FRAMEWORK126 FK error detected: Table: &1 Fieldname: &2 CheckTable: &3 (FK Table) typically indicates a foreign key (FK) constraint violation in the SAP system. This error occurs when an attempt is made to insert or update a record in a table that references another table through a foreign key, but the referenced record does not exist in the parent table.
  Cause:
  
  Missing Parent Record: The most common cause is that the record you are trying to insert or update in the child table does not have a corresponding record in the parent table.
  Data Integrity Issues: There may be data integrity issues where the foreign key relationship is not maintained due to previous deletions or updates.
  Incorrect Data Entry: The data being entered may be incorrect or not conforming to the expected values in the parent table.
  Configuration Issues: There might be issues with the configuration of the foreign key relationships in the database schema.
  
  Solution:
  
  Check Parent Table: Verify that the record you are trying to reference in the parent table exists. If it does not, you will need to create it before inserting or updating the record in the child table.
  Data Validation: Ensure that the data being entered is valid and conforms to the expected values in the parent table.
  Review Foreign Key Constraints: Check the foreign key constraints defined in the database to ensure they are correctly set up.
  Data Consistency: If there are inconsistencies in the data, you may need to clean up the data in both the parent and child tables to maintain referential integrity.
  Debugging: If you are developing or customizing an application, use debugging tools to trace the execution and identify where the foreign key violation is occurring.
