Access to records is not same when impersonated.

[Chindam Priyank]

when one user (X) can see records in a table, but when another user (Y) impersonates X, the records are not visible and a security constraint error occurs, suggests that there may be specific access or permissions set for user X that are not being properly applied during the impersonation.

The table is not global but Security Incident Response application.

Hi @Chindam Priyank 

Ideally, the access should be same unless you have introduced some customization to prevent impersonations to see the records.

Go through the read acls for this table and identify.

If above looks fine, raise a HI ticket, as it is a standard feature, SN support should be able to assist you with this.
