How To Fix USMD1753 - Data model &1, entity type &2: Change of prefix

USMD1753 - Overview

• Message type: E = Error

• Message class: USMD1 - Datenmodel

• Message number: 753

• Message text: Data model &1, entity type &2: Change of prefix

What causes this issue?

You have changed the prefix for a temporary key from &V3& to &V4&.
Either you changed the prefix explicitly, or you changed it implicitly
by deleting or adding a prefix while entity type &V2& is restricted to
internal key assignment (in this case, the default prefix is $).
This can lead to inconsistencies, if entities of type &V2& exist in the
system with temporary key values (which begin with the prefix &V3&).
This also affects all systems to which this Customizing is transported.
