How to make open sales order consider allocated & unallocated stocks in MRP

Question

Dear Experts,
MAT BOM, MAT TYPE, STRATEGY GROUP, PLANNING STRATEGY, Req-DM Req-CU
3. TC180TK   fert                     20                                    KE                        make-to-order
2. TB300TK   halb                    20                                    KE                        make-to-order
1. TA300TK   roh                     10                                   LSF KSL                make-to-stock
As listed above, material in line number 1 is required to produce 2,  and
2 is required to produce 3.
I have open open sales order for material TF180TK(fert).
When I carry out MRP run, stocks of material  TB300TK (halb), that is allocated to this sales order is considered, but unallocated stocks are not considered.
I want the system to consider both stocks, allocated & unallocated stocks.
What settings do I need to effect, to make the System consider available stocks of  material  TB300TK , that is not allocated to this sales order during MRP run using MD01?

Dear
For MTO scinario , any depedent will be either having Account assingement PR or it will pick up the speciall stock (E) based on the Individaul and Cllective Indicator as 1  in MRP4 view .It will never getting reservaed from un-allocated stock ( i beieve u r talking abou Un-restrited stcok ) .This is a standrad behaviour of the MTO cycle in SAP system .
As you have mentioned , that you are using planning startegy 20 -MTO and also you want depdents (SFG and Compoenets in SFG) to be from un-allocated stock .In that case you should not use Planning strategy 20 and also assing Indviaul and Collective Indicator as 2 or blank .It will be purely MTS and you can have sales order with item categoery TAN .
So please  keep Ind/Collective indicator as 2 in MRP4 and try
Hope this helps
