I need some sample about Customizing Synchronization events in MS documentation

Posted on by DP-09071335-0 29
I'm using BC Data-Sync Dataverse Connector Setup.
In Microsof documentation the "Customizing Synchronization" section doesn't provide any sample about using trigger events in CodeUnit  (5345) "Integration Rec. Synch. Invoke".
I didn't find any blog or post about the events.
 
Could someone kindly post some examples with AL code here, please?
 
Thanks!

    Hi,

    You're asking for AL code samples that show how to customize synchronization using events from Codeunit 5345 "Integration Rec. Synch. Invoke", especially since MS documentation doesn’t include examples.

    You're absolutely right while the docs list the available events, they don’t walk through how to use them in practice.

    Here’s a working example to help you get started:

    Sample: Using OnBeforeTransferRecordFields to intercept field mapping
    al
    [EventSubscriber(ObjectType::Codeunit, Codeunit::"Integration Rec. Synch. Invoke", 'OnBeforeTransferRecordFields', '', true, true)]
local procedure HandleOnBeforeTransferRecordFields(SourceRecordRef: RecordRef; var DestinationRecordRef: RecordRef)
var
    SourceContact: Record Contact;
    DestContact: Record Contact;
begin
    if SourceRecordRef.Number = Database::Contact then begin
        SourceContact.Get(SourceRecordRef.RecordId);
        DestContact.Get(DestinationRecordRef.RecordId);

        // Example: Override a field before transfer
        DestContact."Your Custom Field" := SourceContact."Your Custom Field";
        DestContact.Modify();
    end;
end;
     

    This lets you intercept the synchronization process and apply custom logic before fields are transferred. You can also use OnAfterTransferRecordFields if you want to validate or log changes after the sync.


    Other useful events in Codeunit 5345
    • OnBeforeInsertRecord – customize behavior before inserting a new record
    • OnAfterInsertRecord – apply logic after a record is created
    • OnBeforeModifyRecord – intercept updates before they’re applied
    • OnUpdateConflictDetected – handle sync conflicts gracefully
    • OnBeforeApplyRecordTemplate – override template logic during sync


    These events give you full control over how records are created, updated, and matched between Business Central and Dataverse.


    Here’s a helpful link showing how to configure and extend Dataverse synchronization using AL events:

    Cheers

    Could you also provide an AL example using the 'OnBeforeInsertRecord' or 'OnAfterInsertRecord' event, please?
