Mass Change Active Materials Type - All materials ROH - FERT

This is simply a what if question. I deliberation it's wholly insane to do. But I don't marque those decisions.

If you deliberation astir doing a wide alteration to your worldly maestro and I mean each of your materials.   

How agelong bash you deliberation it volition take?

Can it beryllium done?

Will the past beryllium kept?

The background:
We person a constricted magnitude of materials 8,371 - worldly works combinations.  We are trying to inactivate/delete what we don't use.  That's a task going connected now.  We were mid-flight connected an upgrade / that is on-hold now.  

We are utilizing each of OTC, each of BTC, each of PTP but we bash not person the WM level lone the IM.

We usage process orders lone - nary accumulation orders.   Yes, weird.

We person a customized programs, enhancement points, BAPI, BADI, Gateway, CDS, FIORI....  You get the picture.   Around 9000.  I tin bash the scope for these.   It would instrumentality maine rather a spot of time.

We person been connected SAP since precocious 1990s.    4.6C to HANA 1709.   All on-premise but for our analytics.   We person respective 3rd enactment products and APIs to each of them.   I would person to telephone them each individually.

Our consultants are saying it would beryllium done by  the extremity of the year.   I americium saying reimplementation and past I don't adjacent cognize if it could beryllium done due to the fact that of the history.  (That's a gut consciousness and it would instrumentality astatine slightest an twelvemonth successful my sentiment )

Has anyone successfully done this?   Time-line?  Yes we person each benignant of transactions against these materials going connected - each of the time.

Any accusation would beryllium helpful.   It's hard for maine to get implicit my intelligence artifact of don't bash it.

Thank you!

Michelle
