We are migrating from BCS 4 to BCS 6
a. BCS 4 has 7 years of data
b. BCS 6 needs 2 years of history (p12, 2009 to p12, 2011)
c. Go live is p2, 2012 (first collection from SAP R/3 and running of tasks could be p1 or p2)
d. PL00-30 is migrated into BCS 6 (no rerunning of tasks),
e. Conversion of many fields during migration (eg Items, Units, Groups), some fields disappearing, some new fields.
f. Tasks and document types are different in BCS 6
g. Target is the Transaction Cube (to allow future hierarchy re-organisations, restatements etc NOT possible if migrating to a Reporting cube only)
h. We required a clean run of CoI by p6, 2012 (at the latest)
Bearing these in mind, what should the following be;
-First period of consolidation on the cons units?
-First run of CoI in the new system?
-Manual adjs in target BCS system?
Anything else that we should consider?
COLLET Thibaud has a good blog here with the technical migration proposals; /people/collet.thibaud/blog/2010/10/18/sem-bcs--refresh-your-test-system-with-productive-data-using-a-datamart-interface but it doesn't answer these questions.
