Stock confirmation in Checking Horizon

[Former Member]

Hi All

We are frequently facing problems in creating STO deliveries. We have GATP and use the checking horizon to confirm the qty. However several times, we find that stock is available yet the Stock Transfer delivery comes out to be of '0' qty or '0 qty is confirmed.

For example:

i have two STOs for same material from same plant A, with required delivery dates. I have partial stock to fulfill the first STO (with closer delivery date ) and full qty for STO required later.

In this case the stock gets allocated to later STO and nothing is confirmed to initial one.!

I thought system should give preference to delivery dates and would commit in chronological order.

This is getting bigger and bigger concern everyday! Can you please suggest the appropriate way to resolve this, (rather than manually going in BOPI every time)

Thanks in advance

Hi Rahul,

GATP is REAL-TIME atp check. So, results of online GATP check don't depend on the delivery dates, rather they depend on the receipts and requirements situation when the particular Sales Order or STO is created.

You can check that your STO with later date would have been created earlier, and it could get the stock at that point of time.

The STO with closer date would have got created on a later date, and by that time, stock (or receipts) was already reserved for the STO that is for the later date.

This is a very common scenario, and for taking care of this, you should schedule a BOP in background. tcode - /sapapo/bop.

In the BOP run, you can specify delivery date as the criteria. Schedule this BOP to run at a time when your Sales Orders would not be getting created, preferrably towards end of the day.

So, what would happen is that when your create STO, they would get the confirmation as per the availability at that particular point of time in teh day. This is your current situation.

When your BOP would run in the background at end of the day, it would take care that the STOs for earlier date would be confirmed first.

Hope this helps.

Thanks a lot Pavan

BOP is running twice everyday and we have Material Availability date in the sorting profile.

However my problem is when use creates STO delivery, it allocates full qty to later STO and nothing to first STO.. even if there is stock available (part)

Does it have to do anything with event 'B' which does not include Prod Orders in it. As I do have POs yet to be received!

Also in this case can you suggest the best practice or way to resolve it!

Two options I thot:

1. either STO deliveries should exclude the POs

2. Or, even B to include POs..

Not very sure of the process or steps to do either of them, hope you can suggest the appropriate approach even if none of above!

Thanks a lot in advance

Hi Rahul

Based on your description, I assume that Check Instruction for Business Event "B" contains only Availability Check. I would suggest you configure a different BOP sort profile for STO and have Delivery date as a sort critera. As a result, STO with closer delivery date will have higher priority as get the available confirmation. Alternately, BOPI is an option if volume is low enough to justify manual intervention.

Thanks,

Hi Rahul,

Is your ATP group different for the 2 STOs (it depends on material)? Check the ATP group for the 2 materials in the STOs (if the materials are different) in the ATP tab of material master in APO.

If ATP group is different, then go to /sapapo/rrp3 (product view). Click on ATP tab.

Give business event as B. Press enter. Select "Scope of check".

Compare what elements are given as stock and which ones as receipts for the materials. If one of your materials has less receipts (e.g. PO is not considered) or if it misses some kind of stock, then you consider adding PO (or corresponding receipt element) to the check control.

However, if both the STOs are for the same material (or the ATP group is the same), then the situation clearly is of different availability situations at the time when you create deliveries for STO. In this case, only running BOP which considers delivery date could help you.

Hope this is helpful.

Hi Khanna,

What is your checking horizon value?

Is the first STO within the checking horizon and 2nd STO outside the checking horizon?

If this is the case then the result could be correct.

Please confirm.
