Does anybody have the same problem? In MM02 view forecast I can execute forecast and SAP is calculating forecast which I then can see in my MM02 view (for example). Also if I do it in MP30 no problems.
BUT: if I do it via MP38 no forecast result is made. Strange thing is that it shows in the log it did calculate. Also the ' X' in forecast view is not deleted (for initial) after doing MP38. My system has the latest EHP which I think is the problem. If I do exactly the same thing on an older system it works perfectly. I even used the same best practice item (H13/H14). On that system also the ' X' is deleted as it should.
On my new system SAP does re-calculate my reorder point (MRP type V2). So I know it's doing ' something.
