company code change
we need to revise the wrong design, previously, consultants create one company code A001 and
three redundant company codes A002, A003, A005 in 2009, they are all under one controlling area and same currency and chart of account, now we want to remove three additional company codes A002,a003 and a005, and all the configuration, master data and transaction data needs to move into A001 in production. we use AA, GL, AP, AR , special ledger and CO-CCA, IO, so what are the points we need to keep in mind when we do the merge. any suggestion on the steps we need to perform?
how to migrate those FI open items and documents, how about those assets depreciated in half way, any guideline, thanks
