Trying to get RRBIC configured by following this guide: https://help.sap.com/viewer/a682fa6741124711924f679d6159ed85/6.00.31/en-US/148db6535fe6b74ce10000000a174cb4.html
I think all the config is complete & the master data is setup.
As far as I can tell, step 1 wants me to create an internal Customer Service Order with IW31 and step 2 wants me to create an Intercompany Sales Order. I've done both of these steps.
When I run DP93 to generate the internal billing request, I get this error message:
Sales Document XXX: No items found (Message no. AD01243)
Not to be confused with No Expenditure Item found which I see lots of posts for on the forum.
Any ideas on how to fix?
