SMP/E RECEIVE ORDER Command Example
The Receive Order JCL specifies inventory="all" in the Order Server section. What is this parameter?
Release : 15.0
Component : RECEIVE ORDER
By default, SMP/e will create the Receive Order request in some IBM-internal format.
By specifying inventory="all" the request is built in XML format that "all vendors" (like Broadcom) can understand. With "all" specified, SMP/e runs a utility to build an XML file containing the FMIDs and SYSMODs defined in the given product's CSI to be used by Receive Order.
