The settings in the pull down list for Purchase Requests under View options on the General tab of the security profile are listed as:
​
​Own Only
All (Default to Own)
Department (Default to Own)
Allocated Departments
​
These settings control which Purchase Requests are visible to the members of this security profile assuming they have also been given access to the Purchase Request type through the usage permissions. They work in the following ways:

This setting will display only those purchase requests where the user has entered the Purchase Request into FocalPoint or the user has submitted the Purchase Request for approval or the user has been selected as the recipient on the Purchase Request.

This setting will display all Purchase Requests that the user has access to, initially filtering them to a list where the user has entered, submitted or been selected as the recipient on the Purchase Request. The user ID filter can be removed, allowing them to see all Purchase Requests.

This setting will display all Purchase Requests that the user has access to, where the user has a default department that matches the default department of the user who has entered, submitted or been selected as the recipient on the Purchase Request.

This setting will display all Purchase Requests that the user has access to, where the user is a member of a department that the user who has entered, submitted or been selected as the recipient on the Purchase Request is also a member of.
