Hi, we manage an aircraft platform for our customer. We use Material Masters to define the configurations on the aircraft and manage the supply chain. For each Material Master there are equipment records containing a part number and serial number; these are repairable assets that we repair and manage for our customer. On occasion we add new configurations and procure the material. Such as adding a new display, we would create the master for the display configuration, we would them procure 100 of these for our customer. Each display will have a part number and serial number that will be documented against the master as an equipment record. How do we create these equipment records in batch file. We don't want to manually create each equipment record so what information do we need for SAP to create a batch of new equipment records for these new parts and what transaction would we use.
