More in Migration Object Modeler

You're on on-premise SAP S/4HANA and need to open the modeling environment to adapt a delivered migration object, but LTMOM won't launch for a colleague. What are the two prerequisites, and what's the entry point?

In LTMOM you know the object exists but not which project it lives in. The default Object Browser assumes you already know the project — what's the other view, and what can it search that the browser can't?

For the staging-table approach, the modeler's full feature set is huge. Which three application cases does SAP frame as the common reasons you'd actually reach for it?

You need a migration object to do something the delivered template can't. Before you sink time into building rules in LTMOM, what determines whether your enhancement is even possible?

A colleague says LTMOM is only for staging-table migrations, so direct-transfer projects can't customize objects. Right or wrong?
