Information: Document Splitting in Expert Mode

During FI document posting in any transaction the menu option "simulate general ledger" allows user to view the document splitting line item in details using the expert mode. where the business transaction,transaction variant and splitting method are displayed along with splitting details of each item

T Code: FAGL_MIG_SIM_SPL (Program: FAGL_SHOW_SPLIT) can be used to display document spltting details of document which have already been posted.
However, the transaction shows splitting details with regards to the existing customization for document splitting,
Hence if the document splitting configuration has been changes after the document was posted, some inconsistencies may be observed.
