Change the Settlement Receiver on an Internal Order Account
Internal Order accounts may be used for interdepartmental billing.
If a settlement receiver has been used in a settlement and needs to be changed, you will not be able to simply delete it and replace it. Once a settlement receiver has been used in a settlement SAPgui will not allow it to be deleted from the settlement rule. To make the change, put an end date on that settlement rule (To Period / To Fiscal Year fields) and create a second rule using the new receiver, including the From Period / From Fiscal Year fields.
