What causes this issue?

You are editing a text ID which does not have a name which corresponds
to the name range defined by SAP. Text IDs from the SAP standard
version, partner projects, and customer-specific IDs must have separate
name ranges to avoid data loss during release upgrades.
The initial letters Y and Z are reserved for customer text IDs, the
intial letters JNC (N is a digit from 1 to 9, C a letter from A to Z)
for text IDs in partner projects.

System Response

How to fix this error?

If you are working in a customer system, only create text IDs with the
following naming convention:
Initial letter Y or Z
If you are working in a partner project, only create text IDs with the
following naming convention:
Initial letters JNC.
'N' stands for a digit from 1 to 9,
'C' for a letter from A to Z.
If you are working in an SAP development system, only use the letters Y
and Z for temporary test IDs and delete them once the test has been
performed.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
