Hello

we have two options as the starting option.

Option 1: The data from SAP SD / MM system is "shared" to EHS system and then the EHS process runs there

Option 2: the other way around. EHS data is shared using ALE to SAP SD / MM process

Depending on Option 1 or 2: the process to consolidate the system is different

On top: risks can come up if System 1 does have different release / supportpackage than System 2.

Anyhow: your scenario is one of the common ones because of which many SAP customers are starting IT projects; therefore: many IT provider provides services to support exactly your scenario

So one of the most selected options is to select an IT provider which helps you to consolidate the IT Systems.

The move to "S/4 HANA" is then a different story.... (here as well many IT providers are as well supporting services to support this "move". But you should check the benefits and risks regarding the move to S/4 HANA and you should have a good "blue print"; many companies out there use the chance of this migration story to "check any business process" and look for "optimisation"; but it is on your side to select the best option to go on

Hello charles.han,

This depends on what EHS process are set-up.

For exampel, if your customer runs EHS for SDS authoring a client copy wouldn't be enough.

You would need to make sure to copy the generated WWI documents (templates and generated documents) and inbound documents as well - if they are stored in a DMS.

WWI and Expert Servers would need to be migrated as well.

Links to material and vendor master are important - so these keys would need to be 1:1 indentical as well. Some of these objects might have been created on the EHS side - you need to "copy" them as well....

Hope this helps

And to add to that: The shipping history has to be migrated as well.
