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,

Dear Experts,

I have a doubt pertaining to the same subject therefore putting the related addon question here since this thread is still open.

My requirement is to create a clean data for the client. The existing data contains unwanted phrases and references inherited from previous mother company which has now separated. Therefore as an approach, we decided to create new Pure sub, Real_sub and reload the clean data again. But here we want to use 60% of data as is from existing system (phrases etc) and 40% of new data(Replace new Phrases etc) and upload that into new Pure sub OR Real_sub.

To do this, I got an extract of data in excel from existing system. for e.g. There are 500 Pure sub's and there are approx. 1000 characteristics are such for which I have to compile existing and new data and upload. If I take the OCC tool approach, It will be a huge task to create data load templates for 1000 characteristics. Plus this 1000 characteristics will have data/ phrases into it and that multiple will shoot up volume to thousands of entries. This leads to a huge, time consuming and cumbersome activity.

I just want to know if there is any other approach, other then OCC, that can be considered to load the data in new Pure & Real sub specs.

What can be the other tool/ method which will be easier to handle this activity.
