Contact system specialist - Problems with blocking

What causes this issue?

You want to process one or more assets. The System therefore tries to
protect the asset from other use by setting up an SAP-specific blocking
entry.
This leads to an error.

System Response

The System cannot block the asset. The process you want to carry out
is therefore not allowed.

How to fix this error?

Inform your Systems Specialist in order to limit the error.
