What is the difference between V1, V2 and V3 updates?

V1 Update: It is a Synchronous update. Here the Statistics update is carried out at the same time as the document update (in the application tables).

V2 Update: It is an Asynchronous update. Statistics update and the Document update take place as different tasks.

V1 and V2 don’t need scheduling.

Serialized V3 Update: The V3 collective update must be scheduled as a job (via LBWE). Here, document data is collected in the order it was created and transferred into the BW as a batch job. The transfer sequence may not be the same as the order in which the data was created in all scenarios. V3 update only processes the update data that is successfully processed with the V2 update.
