SAP EHS Component reimplementation

[#1]

Dear Experts,

Here I am not seeking resolution to any error but just need a thought that can be helpful. The scenario is, one of my clients parted out from another company but during implementation, probably lift & shift sort, it inherited the previous orgs FM's/ codes/ programs and may be some config as well. Now there are multiple issues that are being faced for e,g expert rules issues (while writing data) , duplication of data, some redundant data which is likely to be inherited from former one. As a solution to this issue they want to go with the approach of reimplement EHS Component again (' clean slate') instead of keep resolving issues. Here is where there are multiple unanswered questions are lingering.

1) While other modules (MM, SD, PP, FICO etc) are running in parallel, is it possible to do a reimplementation of only SAP EHS ?

2) Or is it advisable to go and resolve issues module by module (Product safety- SVT, rep mgmt, Templates, DG, Waste Mgmt. etc.)and clean the system. But here it will be complex task to identify the unwanted data and programs.

3) While going through reimplementation, how can this be achieved in production while other business process are running. Only DG, Rep shipping are integrated with logistic. SVT is still not live due to issues.

4) Even in that case also, Is it possible to clean slate every thing at one go ? Here may be the customization can be copied from a prototype environment and reload the master data again. The major challenge here is integrated functionalities will be on hold till that time.

5) Imp question: Is there any other approach that any one has done it before for such situation.

Not sure if all this questions can be answered, but a small thought / suggestion can be helpful.

Regards,

Ashish

Thank you Christoph for the helpful suggestions.

Considering the risk and complexity to cleanse the system while other business process are live, it is preferable to go in step by step approach is what it seems. ' Clean Slate ' at one go may not be plausible.

Further Impact analysis is needed for

Identifying Unwanted data and deleting that (like there are many unwanted Phrases lying in specifications that were inherited)

OR

Either to create new Pure_sub, Real_sub, Real_Grp, DG_classificaiton with new number range ( needs to be analyzed further)

2) There are many Programs and FM's not needed, deletion of that need to be checked with Impact analysis.

3) Report symbols and wwi code cleansing expected in Labels.

We are further checking on this and welcome any more thoughts.
