In this FICO configuration activity you are able to define tolerance groups which will be used when you post outgoing payments to vendors. They will help clearing small amounts for which will be more expensive to open a dispute.
IMG Path: Financial Accounting (New) -> Accounts Receivable and Accounts Payable -> Business Transactions -> Outgoing Payments -> Manual Outgoing Payments -> Define Tolerances (Vendors)
Table: T043G, T001, T040, T040A, T043GT
When you enter into the transaction you will see a list of already defined tolerances. If you want to create new, you could create it from scratch or use the copy function as in the most of the SAP configuration transactions.
Maintain Company Code and Tolerance Group ID if you need. If you leave tolerance group blank, it will be a global tolerance group for your company code and you will not have to assigned it.
