IBP Dependent Demand of Purchase Products

[robvid]

Hi Gurus

I hope you can help me and guide me whether the scenario describe has a solution in IBP

We have a scenario where Finish Good A is purchased from a Subcontractor. Once in the Distribution Center Product A can be sold as eaches or the business can Subcontract and pay the warehouse for the conversion of Product A (eaches) into Product B (Display Unit). The planner has two streams of demand for Product A:

• Via direct sales of Product A (independent demand)
• Via demand for Product B (dependent demand)

Is it possible to plan the above scenario for Purchase Products? In this case, the quantity of Product A that needs to be outsourced has to be the independent + dependent demand

We are using dependent demand in IBP for Manufacture products without any issues.

In Master Data I have checked and there is a record for the corresponding Production Source Item but when looking at the Dependent Demand Key Figures in the Planning View nothing is coming trough.

Thanks in advance for your help

Hi Roberto,

In my suggestion this a quota issue.

You need separate the the Product A sourcing in Production Source Header MDT.

Maintain 2 sourcing MDT for Product A used in production B. maintain the sourcing ratio and source type P

In second MDT, create sourcing option for subcontractor and maintain sourcing ratio.( Depending on your scenario define sourcing type as T or U ).

Thanks Sandeep

Probably the reason why is not working is that both have Source Type (ST) U. I was not expecting that the Heuristic would have consider this to calculate the Dependent Demand

I will try to change the ST manually in MDT

Thanks for your help

Hi Roberto,

If you have setup Production source item and it should generate dependent demand on input component.

Which algorithm you are using here Heuristic / optimizer?

If Heuristic, then it should generate

If Optimizer, then you also need the master data setup for input component Production source header for source of supply.

Thanks

Hi Girish

Using Heuristic

Both products have record in Production Source Header

Product B has its BOM (Production Source Item) in IBP

Still, we are not getting any demand coming trough

Thanks for taking the time to reply

Hi Roberto,

Can you share some screen shots of MD setup and which KF you are checking the output?

This looks to be straight forward scenario where TS heuristic should generate dependent demand on product B.

Thanks

Hi Girish

This is a really belated, very late reply on my part but honestly I didn't see your comment until I had to come back and do a search on topic very similar to this one. My sincere apologies, I truly value the time of people in the SAP community.

I posted another question related to Subcon (Purchase) products and dependent demands of purchased items

Sincerely

Roberto

Hi,

You can create the two sources of supply for product A and drive the demand based on requirements (Independent or dependent).

For Product B you will have a subcontracting BOM and send Product A receives Product B this is as standard material subcontracting process.

Best Regads,

Thanks Lingaiah

That is how is set up but still, I can't see any dependent demand. I will try changing the source type as at the moment both of them have value U
