• What is the cause and solution for SAP error message CNVMBTCHECK029 - &1| Foreign key &2 does not exist in the parent structure on the sender. ?

  The SAP error message CNVMBTCHECK029 indicates that there is a foreign key relationship issue in the context of data migration or conversion. Specifically, the error message states that a foreign key (denoted as &2) does not exist in the parent structure on the sender side. This typically occurs during data transfer processes, such as when using the SAP Migration Cockpit or other data migration tools.
  Cause:
  
  Missing Foreign Key Entry: The foreign key that is being referenced in the child table does not exist in the parent table. This can happen if the data in the parent table has not been loaded or if there are discrepancies in the data.
  Data Integrity Issues: There may be data integrity issues where the child records are trying to reference a parent record that has been deleted or was never created.
  Incorrect Mapping: The mapping configuration between the source and target structures may be incorrect, leading to references to non-existent keys.
  Data Format Issues: The data being imported may not conform to the expected format or structure, causing the foreign key checks to fail.
  
  Solution:
  
  Check Parent Data: Verify that the parent records exist in the target system. Ensure that all necessary parent records are loaded before loading child records.
  Data Validation: Perform data validation on the source data to ensure that all foreign key references are valid and that there are no orphaned records.
  Review Mapping Configuration: Check the mapping configuration in the data migration tool to ensure that the foreign key relationships are correctly defined.
  Load Order: Ensure that the data loading sequence is correct. Parent records should be loaded before child records to maintain referential integrity.
  Data Cleansing: If there are discrepancies in the data, consider cleansing the data to remove or correct invalid references before migration.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using for any additional troubleshooting steps or known issues.
  
  Related Information:
