ATP Qty check when create S/O

[Former Member]

Dear all

I met a trouble of ATP Qty check.

The case of it is there are two storage location 0001 and 0003 in plant 2001.

Material A are stored in 0001 (7pic) and 0003(5pic).

Firstly I created two S/O for 0001 : S/O.1 for 5pic and S/O.2 for 2pic. (both ok)

Then I move 3pic from 0001 to 0003 by MB1B and MBSU.

Now in 0001 the unrestricted use of Material A is 4pic but sales order is 7pic.

Then I create S/O for 0003 : S/O.3 for 5pic (save ok).

but when I continue to create S/O for 0003 : S/O.4 for 3pic (failed)

The system told me there is no ATP qty.

But according to CO09, there is still 3pic for ATP in 0003.

Can anyone tell me why?

Is the Atp check based on the whole plant level but not storage location level?

How to prevent the case?

if your availability check is on check the tab for availability in sales order , it will give you the idea if quantity is available or not

There you can click Scope of Check, once you click there you will come to know

quanitties may be reserved due to following

Include Reservations, include sales orders(i.e Open) , include dependent requirement,

So all this reservations are taken into consideration if they are ticked

Dear Slam Yang

Can you tell us you are maintaining storage location in sales order?

In OVZ3 you will find checking group is at Material type and plant level, can you tell us what it is maintained daily requirement or Individual requirement.

and what are the settings maintained in OVZG for your requirement class( you can find it from your requirement type(OVZH), which is determined by item category + MRP Type (OVZI)

Dear Jitesh

I can't find any information about plant 2001 in OVZ3 (seems not maintain)

ant the RqTy for ItCa is 011 Delivery requirement.

In OVZG, Flag of AvC(SD availability check) and Rq(Transfer of requirements / Begin assembly order from SD) are both signed for ReqCl : 011

I am a newr, so sorry for misunderstanding your information.

I think if I need to do check when do stock transfer since the stock transfer just consider the qty of unrestricted but not ATP?

By which way to do the available check? User Exit?

Dear Slam Yang

If it is not maintained then create entries for your plant 2001 in OVZ3
