Q - When interfacing the sub-ledgers (i.e., AR, AP, IM) to the General Ledger, must all other users exit Elliott? Or if we are interfacing only AP, can users just stay out of AP, for instance? 

A - The key is that no one should perform any "POSTING" activity in that module during the time when interfacing is processing for that module.  For example: When you interface AP to GL, you should make sure no one posts any AP transactions (AP new voucher transactions, AP checks, etc.).
