PPDS Resource Constraint Planning for Multiple Source of supply

Hello,

We have a scenario, where we are creating Multiple Production versions which CIF to APO with Multiple PDS. In multiple PV different work centers & different BOM has been assigned… We want to do Capacity planning for all Source of Supply.

I see only option is to use SAP_REM heuristic…But we don’t want to use this heuristic, as it is having lots of restriction…

I have tried with SAP PP heuristic for creating planned orders, and then doing capacity planning using SAP_DS_02…Enhanced Backward scheduling & SAP_DS_01 Stable Forward Scheduling … But it is still doesn't select the alternative source of supply…

Is there any heuristic, or running multiple sequence of heuristic which can plan on multiple PDS for capacity leveling …..

Hi Debhashis


Could you please share the solution ?


As per my knowledge this can be done by :

During planning, the system selects the source of supply according to the

following criteria:

Quota arrangements: If the quota arrangement heuristic SAP_PP_Q001 is defined

in the product master, quota arrangements are taken into consideration.

Priority (highest priority = 0): If several sources of supply can deliver on time, the

source of supply with the highest priority is selected.

Costs: If there are several sources of supply with the same priority, the most

cost-effective option is selected.

Adherence to delivery dates: A source of supply that can deliver the required

quantity on time is always used in the production planning run. If the source of

supply selected on the basis of quota arrangement, priority and costs cannot meet

the delivery date for the product, the system selects the next best procurement

alternative in terms of quota arrangement, priority and costs, and checks whether

this source of supply ensures that the delivery dates can be met. Adherence to

delivery dates is therefore a “hard” condition. If none of the available procurement

alternatives can meet the due date, the order is created at a later date (the

alternative with the smallest delay is selected).

Hii Rami,

We have done custom modification to some of function modules, and applied to  the optimizer.

PPDS standard Optimizer does not move orders from one source of supply to another supply. It just moves orders from one Mode to different Mode in the PDS.

Where as we have done such modification, that optimizer call all the source supply and consider them as a different dummy  Mode priority and moved the orders as per the weightage we have selected in optimizer profile(set up time, delay time, delay cost etc).

Hi Debashis

I don't know whether you talk about PPDS heuristic or PPDS Optimizer

PPDS Optimizer move the order to others source of supply according to priorities ,please check SAP OSS FAQ note 1374824 FAQ - Order Creation PP/DS Optimization

Q13: How are Source of Supply priorities picked?

A13: Using the Procurement Priority in the header of the PPM or PDS.

Thanks

Hii Rami,

PPDS Optimizer, does consider source of supply Priorities, Bit it   can;t move order from one source to others.

PPDS optmizer can move order from one mode priority to other mode priority with in a single source of supply ..

example : We run optimizer as resource as a selection  and there are two resource . We do have two PDS  for the below combination

PDS 1 : mat 1 , Resource 1 , Bom 1 (procurement priority 0)

PDS 2 : Mat 1 , resource 2, Bom 1 (Procurement priority 1)

Optimizer won';t be able to move order s from PDS 1 to  PDS2 ..

Optimizer can move order if it is the below scenario:

PDS1 with Mode A: mat 1 , Resource 1 , Bom 1

PDS 1 with Mode B : mat 1 , Resource 2 , Bom 1..

Hope i have answered your query...
