Document Splitting Characteristics in new G/L After go live

[rach2]

Hello,

We need to activate document splitting, we do not need to migrate from clasic GL into a new G/L, because FAGLFLEXT is already populated, but our problem is that currently we only have into the "Assign Scenarios and Customer Fields to Ledgers" the FIN_CCA Cost Center Update, but we need to add the next Scenarios so the new document splittng definition works:

FIN_PCA Profit Center Update

FIN_SEGM Segmentation

We found SAP note 891144 that says:

the following is explicitly prohibited:

2. You are not allowed to change the ledger definitions or temporarily deactivate/activate an assigned scenario or customer field later on (e.g. subsequent FIN_PCA assignment).

My concern is if we add the scenarios mentoned below can cause system errors, problems to the data of the company codes, and if somebody could help us to clarify the project phases.
