Conversion of SNP Planned Orders To PPDS Planned orders

Former Member

Hi,

I have a situation where in the users manually change the SNP Planned orders(keeping the overall amount as constant) in the planning book. Post that when these orders are converted into PP/DS orders some of the orders are lost.

Can you suggest some solution for this behavior.

Thanks

Hi Blod,

I suppose that the conversion is made in Receipt view. In the strategy profile please change the Schedule mode to infinite Scheduling. Same thing for Actions in Case of Scheduling error.

Hope that can help you.

Thanks.

Hi Marius,

No currently the changes are made in the planning book.

Right now the schedule mode is Infinite Scheduling with Planning Direction as Backwards+Reverse.

PS: If we don't make any changes in SNP planned orders then we don't see the Planned Order numbers dropping.

Thanks

Hi Blod,

Did you maintain a PPDS horizon? In witch transaction are you doing the conversion of SNP.Pl.Orders?

Thanks.

Hi Blod,

Please see the below text from the note 481906

Thanks, Marius

SNP->PP/DS conversion


First, the conversion is discussed. If you use this procedure, SNP is used to create all of the planned orders. The SNP planned orders are converted to PP/DS planned orders in a conversion process. This results in the following planning process:

  • SNP planning is used to determine the sources of supply.
  • You want the sources of supply selected by SNP to be transferred to PP/DS planning.
  • SNP plans in planning periods (usually in weekly or monthly buckets). PP/DS plans in accordance with the lot sizes required for Execution. When SNP receipt elements are converted to PP/DS receipt elements, you want the system to distribute the receipt elements to the lot sizes required in the production.
  • Planning/optimization of the sequences and the resource reservations then takes place in PP/DS.

Procedure

===========

You use transaction /SAPAPO/RRP_SNP2PPDS or the report /SAPAPO/RRP_SNP2PPDS to convert the SNP receipt elements in the PP/DS horizon to PP/DS receipt elements.

The quantities of PP/DS receipt elements are no longer changed after the conversion. No procurement planning heuristics are executed in the PP/DS. Of course, you can continue to use all procedures of detailed scheduling and all procedures used for the transfer to Execution for the PP/DS receipt elements. You can therefore use the PP/DS optimizer to schedule and reschedule the PP/DS receipt elements. You can execute DS heuristics. The PP/DS planned order can be rescheduled in the graphical planning table. This planned order can be checked using an ATP check and the conversion to a production order can be triggered in APO.

Settings

==============

This procedure requires the following settings:

  • The PP/DS horizon is greater than or equal to the SNP production horizon.
  • The planning procedure in the product master is set to manual planning.
  • The conversion from SNP to PP/DS is carried out on a regular basis. An SNP receipt element may be split into several PP/DS receipt elements during this conversion (the system therefore creates lots that can be produced).
  • You use an infinite scheduling strategy for the conversion.
  • You must set an SNP planning area and a package size to convert the SNP receipt elements to PP/DS receipt elements.
  • You must execute an MRP planning run at regular intervals (the conversion and the MRP planning run do not have to be performed in a specific sequence or at the same frequency).

Setting The Horizons

=========================

As of APO Release 3.1, you can select a PP/DS horizon that is larger than the production horizon. This can be put to good use here. Set a very small production horizon. This also enables SNP planning to create new planned orders in the short-term area. These new planned orders may soon have to be converted to PP/DS planned orders so that they are correctly sorted into the setup sequence. The PP/DS horizon is relevant for this. The PP/DS horizon can be larger than the SNP production horizon.

Hi Marius,

We are converting it through individual conversion of SNP Planned Order  heuristics

Thanks

Hi Blod,

So, this happened just for changed SNP Pl.Orders!

When you change/save the SNP Pl.Order please check if the changes were updated on ECC side too (you can perform a compare/reconcile with CCR to fix the inconsistencies). Then do the conversion and check the logs as suggested by Tiago.

Thanks.
