SNP PPDS PReq

[Former Member]

Hi ,

I have two purchase req's for the same demand.one from SNP and the other from PPDS

Can any one kindly throw light on this

Thanks,

Hi SS,

Looks like, you have executed SNP run & then PPDS run.

SNP run may have created Pur req at the start of the SNP horizon during SNP run (when there was no Supply element for the demand element) & PPDS run must have created Pur Req as the requirement element was within the PPDS horizon.

Execute SNP run to delete the extra SNP Pur Req.

Hope this helps.

Hi Nawanit,

Thanks for the response

In this case both the Planned orders have the same date. We have define SNP Prdn hor of 2 weeks

There are both the PDS's (SNP and PPDS) available for the product

(I would like to make a correction that we have two plned orders and not two pu req's)

We do not use PPDS . We use only heuristic and optimizer

Thanks,

SS

Hi SS,

Which horizon planned orders are created ? Check the category of the 2 planned orders (SNP:PL-ORD or PlOrd.)

Within 2 weeks (SNP horizon), the order may have been created manually or through Product Heuristic in the Product view.

Beyond the 2 weeks horizon SNP Planned order would be created,.

If the order exist in 2 week horizon, run the Product heuristic to delete the excess orders.

If the order exist beyond 2 week horizon, run the SNP heuristic to delete the excess orders.

Hope this helps.

Hi SS,

For the same demand, if you maintain 2 weeks SNP horizon, system should never create both SNP and PPDS planned orders. Also each, SNP or PPDS, can not create orders in another's horizon...so this leads me to the doubt that some body created one of the orders manually or there is a case like Nawanit described. Both SNP and PPDS have heuristics and optimizer, by the way..

In addition to what Nawanit advised, you can do few more things to find out how the orders are created:

1. Go to transaction /n/sapapo/rrp3 ( product view), enter your version, location, product and check the tab "pegging". This tells you which planned order was created with reference to which demand. If there is no entry in pegging tab, that means the planned order could have been created manually.

2. In the same product view window, type "GT_IO" in the prompt where you enter transaction code to get any transaction ( top left hand side corner- rectangular space). This should take you to a screen with internal details of the orders. Locate your orders using CTRL+F or manually find the order and scroll all the way to the right. There is a creation date/time column. You can see the creation date/time column and get clues if this this order was created as part of any batch job. Keep in mind that these times are in UTC.

3. Check logs - if this is created by the heuristic, you should be able to find the logs through program /sapapo/rsnpdrp1 or if this is PPDS, check the transaction /n/sapapo/rrplog1, you can filter the logs based on product and location in the filter tab.

Hope these help you trace the issue.

Hi,

How can PPDS create a demand out of the pu req which SNP has created?

Can you please provide me with additional tips like GT_IO in APO. This is very smart and helps a lot

Kindly share some more if you are aware of any in APO

Thanks,

SS
