Dear Team,
I have a scenario of Quota arrangement.
Suppose I have a requirement for 20 Qty, of material number "91"
I am maintaining a Quota for Two vendors equally
Vendor 210120 will supply 10 Qty , similarly Vendor 210116 will supply 10 Qty
Following pre-requisites steps are maintained already in following screens.



Here in the above screen,
In Item overview table we can see, Two PR’s are assigned to two different vendors w.r.t Quota system.
MY QUESTION IS :
But the same, in Item detail tab Source of Supply-The following data has to populate automatically!!?, ( Blue encircled fields) why it is not populating automatically!!?
These three field are empty, these I can manually fill and assign using pencil icon.
But suppose I have hundreds of PR, How should I assign them at a single time to the corresponding vendors, without assigning manually!!!???
Because in further step: I have to do Automatic PO process ( ME59N) , which should get generated automatically.
Kindly show some light on this scenario team.
Thank you
NSK
