Special Migration Scenarios 
In addition to the migration scenarios with and without document splitting, there are also other scenarios that are not described explicitly here. There are the following reasons for this:
● SAP is not familiar with all possible initial scenarios and their specific use at the customer site (such as special purpose ledgers)
● Some scenarios are not very common (such as the use of special purpose ledgers to portray parallel accounting).
● The company code approach for portraying parallel accounting is not recommended by SAP.
