Question

Dear All,
My requiremnt is when i pass billing documnet my corrosponding accounting document - assignment field need to cpature Material (MATNR) from delivery document.
I have two options. One i can do it with user exit where BSEG will pick MATNR from corrosponding billing document.
Another option is i can do it with config of sort key. I made one sort key where in field 1 i put MATNR. And assign this sort key in Recon G/L master of corrosponding customer code. But it is not working.
Accounting document - assignment field is blank coming. Even i tried to assign that sort key in customer master but it is of no use.

Hi
1. When you give the sort key the assignment field in FBL3N gets filled with the value that has been gien in the sort key.
2. The second use is you can sort the assignment field in FBL3N.
Another functionality or use of sort key is
Where Sort Keys are created
Use Tcode OB16.
Why we are using sort keys.
Straight answer to this is sort key offers great help in Automatic Clearing.
First we understand how does it function. If you have created Bank GL and there you have used 001 (posting date) as sort key then whenever you make entry for that bank Gl your sort key "Posting date" is automatically updated in "Assignment" field unless you manually insert anything in assignment field.
Let's take a simple example for why sort keys are helpful.
Suppose, there is GR/IR account created with sort key 014 (Purchase Order) so at the time of
1. Goods receipt Purchase order with item no will automatically filled in assignment field.
Inventory dr. 15000
GR/IR cr 15000.
In GR/IR account item Assignment would be 150000 10.
2. Invoice through MIRO will also feed Purchase Order with item no in assignment field.
GR/IR dr . 15000
Tax dr. 5000
Vendot cr. 20000
In GR/IR account item Assignment would be 150000 10.
Now your entry is over. There are large number of such entries posted in the period for the GR/IR account.
So, manual clearing becomes very tedious for GR/IR clearing account. In order to avoid that Automatic Clearing program is configured in OB74, where you give field ZUONR i.e. assignment in first criterion. So, line items with same assignment and amount will be cleared automatically upon F.13 transaction.
