How To Fix USMD2200 - Action not possible; different change requests for source and target

SAP Error Message - Details

• Message type: E = Error

• Message class: USMD2 - Master Data: UI Modeling

• Message number: 200

• Message text: Action not possible; different change requests for source and target

What causes this issue?

It is not possible to insert an entity at the position you selected in
the hierarchy. This can be due to one of the following reasons:
You want to move an entity in the hierarchy. The higher-level node of
the original position in the hierarchy is in change request &V1&, but
the higher-level node of the new position in the hierarchy is in change
request &V2&. It is therefore not possible to move the entity.
You want to insert an entity in the hierarchy. However, the entity is
already assigned to change request &V1& as a higher-level node, but the
higher-level node of the place of insertion is assigned to change
request &V2&. It is therefore not possible to insert an entity in the
hierarchy at this position.

System Response

The entity is not moved / inserted.

How to fix this error?

Finalize one of the change requests so that one of the higher-level
nodes is released again and can be included in the other change request.
Then carry out the action.
