Interface between SAP and AS 400 system

[raghuram2]

Hello,

Currently all warehouse master data is maintained in a legacy system (AS400) and all warehouse activities/processes like Inbound, outbound/internal processes are executed in AS400. For example, for inbound process, the inbound delivery is created in ECC system and then transferred to AS400 system where it is used for putaway to the final bin. Similarly for outbound processes, outbound deliveries/shipments are created in ECC and the same is transferred to the AS400 system where the picking is done.

To summarize, the relevant documents like inbound/outbound deliveries are created in ECC with which further Warehouse activities (Put away/picking etc) is carried out in AS 400 system.

Now there are lot of Z developments/messages developed for transferring the data from ECC to As400.

What I am interested is if I set up the warehouse which is currently present in AS400 as a Decentralised warehouse/Lean warehouse, can we make use of the standard interface functionalities so that we can reduce the Z developments. Please note that even if we set up a DWM, the warehouse activities like Put away/picking etc still happen in AS400.

But by setting up of this, will it be of any use in terms of using the standard interface functionalities? if yes, please share some details as to how it can be done

Any inputs will be highly appreciated.
Regards,
Raghuram
