Decentralized EWM on an SAP S/4HANA stack

Dears,

I would similar to understand, what would beryllium the imaginable interaction of changing beneath configuration connected already moving S/4HANA on-premise 2021?

SAP Customizing Implementation Guide -> SCM Extended Warehouse Management -> Extended Warehouse Management -> Enable Decentralized EWM

It is important to clarify, that we ARE NOT utilizing EWM (neither Emended nor Decentralized), but for immoderate reason, during postings successful MIGO transaction, strategy is "looking for" EWM tables to update (checked successful de-bug mode). During this clip of approximate 30 mins, documents posted are locked successful SM12. We recovered out, IF Decentralized EWM is activated successful SPRO, the strategy skip searching and straight station without DB block.

Help accusation says:

Note:

You indispensable not alteration the configuration of whether EWM is embedded oregon decentralized erstwhile transaction information exists, due to the fact that this would disrupt existing processes and documents.

For much accusation astir EWM deployment options, spot SAP Note 1606493.

So, we person transactional data, BUT it is not successful EWM tables (as we didn't activate EWM), hence question is: In case, we alteration acceptable up to "Decentralized EWM", erstwhile we really don't person such, whether to expect immoderate antagonistic interaction connected system?

Thank you!
