Restricted check function in the case of selection by identifier

What causes this issue?

You are restricting the number of entries to be evaluated using the
selection field for the identifier.

System Response

SAP programs that use the secure storage can transfer a list of entries
that they expect to be in the secure storage to the program
"Administration of the Secure Storage". If the program does not find one
or more of these entries, it generates a virtual entry in the entry
overview with the error message SECSTORE 057 ("Entry required by
application ... is missing in the secure storage").
You have now deactivated this check.

How to fix this error?

To perform this special check, either leave the selection field for the
identifier empty or select a specific application using the selection
field "Selected Application".
