New GL Document Splitting Activation Migration Project

Former Member

Customer runs on SAP ECC 6.0 with new GL active since Jan 2010. Now to generate Profit Center level FS, wanted to activate Document Splitting.

The customer is decided to go for sap gl migration cockpit which could support to migrate open items for the FY 2012.

As suggested by SAP the migration date should be start of the new fiscal year say 01.01.2014.

Assuming the activities like test migration, validation session (Done in Production Copy), corrections to Production consumes max 8 weeks (As conveyed by SAP) & the production migration a weekend, what could happen to the data being posted during this period (Say Jan 01 2014 to Feb 28 2014).

Would those data also fall under migration plan of production weekend, am looking for expert opinion to address to the customer.

Dear Madhu

I could understand from your reply that Phase 0 refers old fiscal year with Open Items which need to be migrated. In Phase 1 the migration happens. Phase 2 Go Live

December 31 2013 - Year End Closing

January 1 - January 24 2014 - Migration Test followed by validation session and changes in the production settings (In a Test system with Production Copy)

In Parallel during this period there are materials & asset documents posted with account assignment say profit center and relevant payables are not updated (as document splitting is yet to activate).

January 25 - 26 2014 - Production Migration

My question is all open items would be updated with account assignment, Clarify whatever the documents posted during this period as mentioned above, would those also be considered for migration?

Your quick response in this situation is appreciated

You define all the necessary split configuration before phase 1, so that as from 01/01 your split information is already built up, though no posting happens in New G/L. During the migration, these documents are posted in New G/L based on the split information. As for the migration itself: obviously, the system should be closed during this period, so no documents are posted before the migration process is complete and New G/L is activated.
