RE: Trial Balance Issue - Business Central
We prefer to use a suspense account or opening balance account like Daniel suggested above. All the methods discussed will work, but we try to avoid multiple postings into and out of the AR/AP control accounts. When users come to drill down into these accounts, it can look messy with a lot of entries that net to £0.
Typically we will post the opening TB, but instead of posting to the control accounts, put these balances against the suspense accounts. So AP and AR go to suspense (bank also needs dealing with, separate issue on reconciling items!)
Then, when posting the individual opening balances, the posting groups will flow these through to the right place in the GL, but importantly you'll only have one set of entries in the GL for AP/AR, and you'll be able to drill down into the GL balance and see what entries make it up.
Just make sure control accounts in the GL and the sub-ledgers have the same balance :) You might be surprised how often this isn't the case!
