Can we use SNP PDS in Multi level ATP ?

Question

Hi All,
We do CTM planning with existing SNP PDS In APO and now we want to explore to use the Multi level ATP functionality for GATP.  I know, MATP can create the ATP trees if the stock is not available and these can be converted into PPDS order.
My question is, can we use SNP PDS for this purpose?
Thanks,

Hi Abhilasha,
There is no such specific mention anywhere in the literature that you cannot use SNP PDS for MATP. The only downside to using SNP PDS is that SNP PDS are meant for mid to long term planning and the activities/operations in SNP PDS are usually not in detail i.e only important activities or bottle neck components are usually used which will not always facilitate detailed scheduling.
On the other hand MATP creates ATP tree structures by plan exlosion(which can be SNP/PDS) and saves the requirements groups(component requirements of header level) with dates/qts and source of supply. It uses PPDS component to convert these ATP tree structures into PPDS planned orders depending on the conversion horizon/requirements dates. It does that by reading the source of supply, requirements dates and quantities from ATP tree structure and by plan explosion.
When MATP planned orders are created you should no longer plan them with automatic planning run as that will cause re-explosion of the plan and might cause incorrect down stream requirements if you had had substitutions at component leve during MATP check. In planned orders, you have an option of changing the allowed sources of supply (in source of supply section). But for orders created by MATP, you will not be allowed to change the source of supply field from SNP PDS to PPDS PDS in the planned order because it will re-explode the plan. So you can decide for yourself if you can use SNP PDS as source of supply for PPDS planned orders.
Hope that answers your question.
