Decentralized EWM

Former Member

Experts,

I am newbie to SAP EWM. I learnt that EWM is decentralized. I would like to understand the prime reasons behind this architecture. Communications between ECC & EWM happen thru CIF APO interface. What are the business benefits of doing this setup/why does SAP recommend this setup.

Also i learnt that SCM EWM can also be deployed centralized. Central installation requires ECC 6.0 with EhP3 and SCM 5.1.

What should be the driving factors behind centralized or decentralized installation.

Please share your valuable inputs.

BR,
Aspire

HI Aspire,

Globally all best of breed solution are independent WM system..

Decentralization concept give you flexibility of a single EWM system integrated to multiple ECC system of single ECC to multiple ECC..Also if requireb you can connect an ECC and a non SAP system to same EWM system.there are many more technical advantage as well..

Hi Aspire,

Centralised resides on the same system and uses the same database as

the ERP. If the ERP goes down, means your warehouse management system

also goes down. Decentralised means the WM system resides on its own

system and has its own database. Master data and transactional data

must be interfaced from the ERP into the WM system, so master data

such as customers/vendor and materials and transactional data such as

inbound and outbound deliveries is interfaced from the ERP into the

WM. If the ERP system is not available, the decentralised WM system

can continue to work at least with the deliveries already interfaced

into it. And will batch the communications back to the ERP until it is

available again. Decentalised is mainly there for performance and

resilence reasons, but also to allow the use of more advanced WM

solutions than is provided within the ERP software suite, i.e. EWM

when using SAP ECC ERP. Although EWM can now be installed onto the

same server as that running the ERP.
