what is customer reconciliation account? If i donot maintain in customer master data, what are it's effects
In SAP, users can specify an account type as being a reconciliation account. Each and every sub-ledger account should have a corresponding reconciliation account in the general ledger. SAP automatically posts an entry in the reconciliation account as and when an entry is made in sub-ledger. To take a simple example the "payable account for goods and services" is an example of a reconciliation account for suppliers. In the reconciliation account field, the user should enter vendor.
So you may be thinking what is the main use of a reconciliation account in SAP?
Well, with reconciliation accounts, one can generate a balance sheet or profit and loss account at any time, since amounts posted in sub-ledger are also reflected in the general ledger. One final note, I personally would advise SAP R3 users to check the balance of reconciliation account and match it with the corresponding sub-ledger account, to ensure that they match.
