Creating inbound Sales Orders IDOC within SAP

Hi,

I receive a flat file containing sales order information. I would like to create inbound Sales Order IDOCs from this flat file. I know I can use BAPI_SALESORDER_CREATEFROMDAT2 to create sales orders however I would like to retain the benefits of IDOCs e.g. error retention and re-processing.

There are a number of functions MASTERIDOC_CREATE* to create various IDOCs but I can't seem to find one for message type ORDERS. I know I can create a 'Z' version but would like to avoid that as much as possible as development budget is tight.

Any help would be greatly appreciated in the form of reward points.

Thanks and regards,

Liam
