In this step you define so-called release approval groups. You then enter these in the master records of your customers and vendors.
You require release approval groups in the later steps "Allocate release approval paths" and "Allocate release approval procedures" . On the basis of the release approval path and a certain amount, the system determines which subworkflow is triggered by the payment release and who is to release the payment. If a release approval group is not defined, then the system subsequently accesses the data with the initial release approval group.
