In transit stock & Negative stock in SNP

[Former Member]

Hi,

I need some input on behavior of following stocks in APO:

1     In transit stock:

     Whether to transfer in-transit stock to APO? Will this cause duplication of receipt as there would be a STO between the 2 locations for the transfer of stock.

     Will system considers it as duplication while calculating the total receipts?

2     Negative stock

          We have some materials in ECC for which negative stocks are permitted. How negative stock will behave if these are carried to APO.

          We are using optimizer as planning tool in SNP.

regards,

Mohit

Thanks Rajesh & Mike for the response.

Rajesh - For In-transit stock, does it mean that when there is in-transit stock, system will not consider STO as receipt element, it will only consider in-transit stock as receipt element at the destination?

(Considering that the complete qty is in-transit against the STO).

Can we see in the STO in APO some data on this?

Hi Mohit,

Consider an example.

You have a confirmed STO to transfer stock of product x from source A to destination B.

STO quantity: 5000 CS, start date 7/17/2012, and end date 7/19/2012.

If you create the outbound delivery for the above STO for 5000CS of product X and complete the PGI,

Source Location: Inventory reduced by STO quantity and STO will be disappeared from distribution demand.

Destination Location: STO will be disappeared from distribution receipt and in-transit will be increased by 5000 CS. Thus, at destination, in-transit stock will represent the receipt element.

If you check the details of in-transit, you can find the STO number. Based on that you can find the required details in ECC. 

Thanks,

Rajesh

Mohit,

1. In-transit stock: Upon PGI, the shipment quantity will be reduced from distribution receipt (distribution demand for source location) and in-transit quantity will be increased for the same time period. Upon goods receipt, the in-transit quantity will be reduced and stock on hand will be increased at destination location by the same amount.

2. Negative stock: These stock are allowed to enter into APO. Please check the following link for details.

Optimizer will consider it as a demand element similar to safety stock (soft constraint).

Refer the following link on visibility of negative stock in APO.

Hi,

Unfortunately, the optimizer will not consider negative stock.

Hi Mike,

It's good to know about this constraint. I worked with a beverages giant on their DRP functionality in the USA. They use optimizer extensively for simulation, quota management, and network planning. In one of the simulation study, negative stock was passed and optimizer considered it as soft constraint. The system release was SCM 5.x (it would have been upgraded now). However, the optimizer functionality was heavily customized by SAP with custom interface to update the input data to optimizer without touching master and transactional data. I was under impression that negative stock would be considered by default.

Thanks,

Rajesh
