- SAP provides a predefined set of checks.
- You can check for certain net amount limits, for example after billing. Then the billing document can be checked, reversed, released, or it can also be manually billed.
- After invoicing, you should check for gross amount limits. Credit checks should also be carried out during the invoicing process and not before, as clearing takes place during invoicing (budget billing payments, payments on account, cash security deposits).
- You can create your own outsorting checks and include them in the billing or invoicing program without modification.
- Outsorting can occur after billing or invoicing.

- Outsorting can occur after billing or invoicing.
- Different checks can be carried out according to the time of the outsorting.
- On this slide, you can see the checks provided by SAP in the system.

- The system supports automatic checks. The agent can also store a manual outsorting in the contract.
- The agent must check the outsorted billing documents on the screen and can either reverse the billing or release it for invoicing.
- The agent can use a report to display the outsorted billing documents. He/she can also process them using a workflow. To display the outsorted billing documents, two events (OUTSORTED and RELEASED) are available for the BILLDOCAUT business object. To process them, the OUTSORTDISPLAY method is available.

- The outsorting groups are usually stored in the rate category and can be overridden in the contract in special cases.
- The actual checks are found using a customizing table from the combination of the outsorting group and the billing procedure.

- You can create additional outsorting checks. The check programs are small ABAP/4 function modules.
- The check programs in the billing are subject to a naming convention. They start with ISU_VAL_.....
- The check programs for invoicing are start with Z.
