Planned Delivery time is not considered while creating Purchase Requisition

[Former Member]

Hi,

For materials to be procured from outside ( another plant in our case) , we have defined Planned Delivery time in Product Master .

Situation is: If demand is on 01/05/2009, system is generating a Purchase req on 01/05/2009( start and end date is same), when we have maintained 3 days of Planned Delivery time while running SNP Heuristic. In our case we dont have any procurement relationship( where we can also maintain planned delivery time) and TLane duration is Zero.

If we maintain Duration is TLane , system is calculating it correctly, in that case start date is 3 days back ie on 29/04/2009 and end date is on 01/05/2009, which is what we want.

So, why the system is not considering planned delivery time while running SNP Heuristic???

Please help with your suggestations,

thanks,

Priya

Hi Priya ,

Can you please share your experience and approach you finally adopted in your design to get the required results?

thanks ,

Dear Priya,

Planned delivery time is relevent to determine whether the product can be procured within the requirement date. In your case since the requirement date is 01/05 which is well beyond 3 days, the Plan Del Time is not of much relevence.

Had your requirement date been very close (say today is 15/4 and requirement is 17/4), the system would show a PR with receipt date as 18/4 that is 3 days from today.

Plan del time is relevent in another way. If you cif the PR to r/3 and see the same in R/3 you will see a release date which reflects your planned delivery time. The release date in your PR should be 27/04.

The transfer of demand to source location 3 days in advance is achieved only through transport duration. That indicates that the material should be ready and leave source location at least 3 days earlier if transportation takes 3 days.

As some one has suggested, the time taken by source location to produce the material is handled by planned delivery time/ inhouse prod time at source location.

Dear Priya,

The system behavior is correct.

Planned delivery time is generally maintained when the source location is not part of your supply chain model.

SNP heuristics does considers Planned delivery time but that does not reflect in start date of demand at source location. If you want the correct start date in source location then you should maintain correct transportation duration in T Lane.

Dear Vaibhav ,

Could you please provide any documentation (SAP note/help.sap)on your first statement i.e. Planned delivery time is generally maintained when the source location is not part of your supply chain model. As in the F1 help of planned delivery time in product master it says "The planned delivery time is used differently in heuristic-based planning and optimization-based planning:

SNP heuristic: The system takes into account the planned delivery time with both types of external procurement; both when the source location is defined in the supply chain model and when it is not known. If you have also defined an SNP stock transfer horizon, the system uses the larger of the two horizons.

-- Regarding second point you stated PDT does not reflect in start date then where & how does it is considered in planning relevant data.

It would be of great help if you provide some document.

Thanks in advance..

you have to maintain the Planned delivery time for the product at the supplier location. and not at the receiving location So Please check if you have maintained at the supplier location

Hi Priya,

Please check whether snp stock transfer horizon is maintained. If it is the case, ie if you maintain both planned delivery time and snp stock transfer horizon, the system considers the larger of the two horizons in SNP heuristic.
