Transfer of Service (RMA) Order 
This function enables the transfer of service order data from SAP ERP to SAP ME to create the corresponding RMA shop order in SAP ME (see Shop Order).
Integration
The customer repair order is used by sales in SAP ERP for recording all the business processes that are involved in processing faulty goods that a customer sends in for repair.
When you enter the service product and serviceable material in the repair request item, the system creates a return order item automatically for the serviceable material. This is triggered by the goods receipt of the serviceable material.
The RMA shop order is used in SAP ME to authorize the return of manufactured material from a customer to a supplier for a corrective action. A material may be returned for repair, re-configuration, or disposition in some other manner and may be finished goods, subassemblies, or components.
Prerequisites
SAP ERP
You have created a service product and service object (see Master Data).
You have created a customer repair order with a service product (see Creating a Sales Order with Service Product).
You have created a user status profile and have assigned the profile to the service order type (see User Status).
You have configured the system for ALE communication to create and transmit IORDER IDocs (see Customizing for ALE for Communication with SAP ME).
Activities
A service order is automatically created from a customer return in SAP ERP (see Actions for Managing Repairs Processing).
You send the order to SAP ME using the IORD transaction.
SAPMEINT does the following:
Creates the corresponding shop order of the RMA type (see Shop Order Maintenance) and a routing (see Routing Maintenance)
Performs RMA shop order receipt (see RMA Shop Order Receipt)
Performs RMA SFC receipt (see RMA SFC Receipt) sending the query to SAP ERP:
If the BAPI does not return any serial numbers, the system automatically creates SFC numbers based on the order quantity.
If the BAPI returns serial numbers that do not exist in SAP ME, the system creates SFC numbers based on the serial numbers provided.
If the BAPI returns serial numbers that exist in SAP ME, the system uses these SFC numbers on the RMA shop order.
