User Permission Not Applied On Quotations

Hi,

We assigned User Permission to a user to limit his access to a certain Customer, which is applied to all doctypes.
The user permission is applied to other doctypes such as Issues, Sales Order, Sales Invoice but is not applied on Quotations.

Has anyone encountered the same? And how did you resolved this?

Thank you.

Quotations are probably sent to Leads and hence the user permissions aren’t getting applied. Can you check if the quotation has the customer field?
