MRP for special procurement 40
Dear SAP gurus,
I'm wondering about the use of special procurement 40 in MRP.
As my understanding, it's a standard code in SAP which is assigned to procurement type F (external procurement).
In my case, i've already maintained the supplying plant in the config for special proc 40.
And in the material master, I assigned it with proc type F and special proc 40.
However, when I run the MRP, it always results a standar PR instead of Stock Transport Requisition.
and the weirder, it will result a Stock Transport Requisition when I change the proc type into X (both external proc and internal proc).
So my question is, what's actually the proper setting to have a Stock Transport Req as result of MRP?
is it proc type F (and maybe another config I missed?) or it's correct to have proc type X (any reference on this?) ?
Appreciate much for any answer.
