PReq not generated from Service Order SM03 using Control Key SM02
The PReq is not getting generated for Control Key SM02 for service order SM03. I am using PReq generation as "Immediately". The issue is I am filling all the required fileds in the External Processing Operation Popup Screen & saving my Service Order. After that when i check the Document flow - there is no Preq number & in Actual Data for External opration, i find the fileds i have filled in the Preq popup screen as blank (such as Material group, Purc. grp, cost element, vendor etc). I have checked the config also, but cant find any clue.
