POS - Check permissions at the beginning of an operation/function

Hi all, if we start an inbound operation on POS, we have the option to create a new purchase order. We don´t need that function and want to disable it for our users. So we withdraw the permission from the users.

Unfortunately the check for the permissions is at the end of the process (when you want to confirm the new purchase order) and not at the beginning.

So it would be great, if the permissions of the user would be checked right after the click on "New purchase order".

Actual behaviour:

• Start new inbound operation
• Create new purchase order
• Select vendor
• Click confirm
• Message "Manager-Sign in" is required

Desired behaviour:

• Start new inbound operation
• Create new purchase order
• Message "Manager-Sign in" is required

Best regards
