Invoice Creation and Generation (ERS) (SAP Library - Third-Party Order Processing (TPOP))

Invoice Creation and Generation (ERS)

Use

Customer Invoice

The following options are possible for a third-party item:

· Order-related billing according to order quantity

· Order-related billing according to delivered quantity

The latter is only possible when the vendor/supplier sends an advanced shipping notification (ASN). In this case, the billing due list is updated when the ASN data is transferred to the sales order.

The vendor invoice can either be received using EDI, entered manually in SAP SPM (Invoice Verification, MM-IV), or generated automatically with the evaluated receipt settlement (ERS) procedure, provided the appropriate indicator is set for the vendor.

On saving the vendor invoice, a message that updates the document flow of the original sales order is sent to SAP CRM.

Dependencies Between Customer and Vendor Invoice

In the SAP SPM system, the following alternatives for the invoicing process are offered:

· Vendor invoice before customer invoice:

The customer invoice cannot be created before the vendor invoice has been maintained or generated by the system. A billing block is set in the billing due list item when this item is created, and no vendor invoice has yet been created. The creation of the vendor invoice triggers a message to SAP CRM, which then releases this billing block.

· Customer invoice before vendor invoice:

The vendor invoice cannot be released or generated before the customer invoice has been created. This is only supported when the ERS procedure is used. The ERS report generates invoices only for those items that have already been billed in SAP CRM.

· There are no dependencies between vendor and customer invoice – both invoices can be created independently of each other.

Configuration of the alternatives is a global, client-dependent setting.

Note

For a supplier/vendor, you can use transaction MRER to define that an ERS run is allowed. SAP SPM (Financial Accounting - FI) either transfers the amounts or settles them as receivables against the supplier.
