Checking for user-assigned roles

The NAV system checks permissions every time you look at data or run an object, but what if you need to check permissions manually? This recipe will show you how to examine a user ID to check for a specific role.

How to do it...

Create a new codeunit from Object Designer.
Add a global function called VerifySecurity that returns a Boolean value named HasPermission.
This function should take in three parameters:

Name

Type

Length

RoleID

Code

20

CompanyRequired

Boolean

SuperAllowed

Boolean

Name	Type	Length
RoleID	Code	20
CompanyRequired	Boolean
SuperAllowed	Boolean

Add the following code to the function:

HasPermission := CheckUserId(RoleID, CompanyRequired, SuperAllowed);

Add a global function called CheckUserID that returns a Boolean value.
This function should take in the same three parameters as the VerifySecurity function.
Add the following local variable to the function:

Name

Type

Subtype

Session

Record

Session

Name	Type	Subtype
Session	Record	Session

Add the following code to the function:

Session.SETRANGE("My Session", TRUE);
IF NOT Session.FINDFIRST THEN
EXIT...
