To propagate custom fields in Business Central, you copy data from source documents and journal lines to posted entries and ledger records during the posting sequence. This ensures data consistency across sales, purchase, transfer, and journal workflows without manual updates.

The best way to copy custom fields to posted sales invoices and ledger entries is to automate the transfer during posting. This eliminates manual data entry errors and guarantees that custom tracking data appears correctly on all resulting posted and ledger records.

Pattern selection for AL field propagation works by automatically determining whether to use Pattern A (TransferFields) or Pattern B (EventSubscriber). The choice depends entirely on the specific implementation of the underlying posting codeunit to ensure compliance with posting logic rules.

Yes, this field propagation approach works with transfer order posting sequences. It comprehensively applies across sales, purchase, transfer, and journal posting sequences in Business Central to maintain custom data consistency throughout the entire ledger entry generation process.

Custom fields disappear after posting documents in Business Central because they are not automatically copied to posted entries by default. You must explicitly implement field propagation logic to transfer custom data from source headers to their posted counterparts and ledger records.

No specific external dependencies are required to automate field propagation in AL development. The skill provides the necessary scripts and references to implement the automation directly within your Business Central environment using standard AL patterns.
