Text &2 not available for layout set &1

What causes this issue?

In the form &V1&, a reference exists to text &V2& (text ID &V3&,
language &V4&). However, this text is not available in the current
client. This may be due to one of the following reasons:
The text is only available in the original client.
The text is not available in either the original or the current client
and should therefore be created.
RESET N1

System Response

The text cannot be evaluated while the certificate is being created.
Information and logical queries could be lost for this reason.

How to fix this error?

Check your entries in form &V1&. If required, create the text &V2&.
If the text is only available in the original SAP client, copy it in
all languages (if necessary) from the original client to the current
client.
To do this select Tools -> SAPscript -> Standard text -> Utilities ->
Copy from client.
