Negative Stock at Interim Storage type

[Former Member]

Hi Gurus

We have created an interim storage type 800 and Stock removal and placement strategy is R. The allow negative stock indicator in unchecked.

When the Production order is created , it created a TR and TO in the background. The system allows to confirm the production order eventhough the allow negative stock is unchecked for Storage type .We have also not checked the allow negative stocks Allow negative stock for each storage type.

How ever when production is confirmed without confirming the Transfer order generated for the production order, systems confirms the production order and no error is generated. When I look in LS26 for the component a negative quant is created with the production order number as the dynamic bin.

Could you please advise what I am missing in config, which can stop the production confirmation until the component TO is confirmed.

Thanks a lot for your help

Hi

Firstly SAP supplys Interim st types which should be sufficient for production (901. 914)

Interim st types should begin with 9

I believe that interim st types automaticall allow negative stocks as this is a basic requirement of these st types.

I hope that this helps

Hi,

it is as Frenchy describes it. Interim storage types always "allow" negative quants. The flag in the storage type setting has only an effect if the negative quant would be created by a WM movement. But in this case it is triggered from IM. I don't think you can avoid that.

Hi Sunny,

The staging process is like this.

First when you stage from pick list, a TR is created with WM Movement type 319. You have to convert it to TO. Then Material transfers from permenant storage type to 100 by confirming TO. At the time of confirmation of Production order, Material is issued from 100.

In your case, You have not confirmed the TO. Even then, Material is issued from 100 because allow negative stock indicator is checked in 100.

One more important point is there is no impact of 800 storage type here because 2-step picking will be triggered only with Group of TRs not with individual TRs.
