Purchasing group choosing priority

[former_member1182649]

Hello Gurus,

Hope to get your professional introduction. The case is like below:

Item 2000 0000, its purchasing group in material master data is "100",

This item has a source list, contains vendors "1000", "2000" and "3000", each vendor is assigned to a purchasing group:

Vendor "1000" is assigned to purchasing group "100",

"2000" is assigned to group "200",

"3000" is assigned to group "300".

Then how can I make the purchase requisition be assigned to group "300" automatically when running MRP without changing the material master data?

Thank you and looking forward to your professional reply!

What value do you have for the MRP field in the source list. It should be set to 1 for the vendor that you want MRP to use (in your example it should be for Vendor 3000). My guess is that the value is currently blank for all three source list entries so it's picking the first hit it gets (probably 1000).

You also didn't say whether you were using info records. In all the systems I've worked on we always use an info record so I'm not sure if MRP gets the purchasing group from the vendor if there isn't an info record. If you do use info records than the purchasing group in the info record for a particular material/vendor combination should override the value that is in the material master.

Hello DOC11,

Extra info. for this case:

Vendor "1000" is assigned to purchasing group "100", with info. record PB.

"2000" is assigned to group "200", with info. record PB.

"3000" is assigned to group "300". with info. record PL.
We hope that even in master data it's assigned to 100, because "3000" has a PL, so after MRP running, the plan order / PR will be assigned to "300".

Months later, if "2000" has a PL info. record, while "3000" PL is expired, it will be auto. assigned to "200".

Is it possible? Thank you!
