Axapta: Validate Access to return value from display method - Ax 2009

I was working on a report today and after compiling it I saw that the compiler gave me some Best Practices errors.

Basically the error said : Validate Access to return value from display method.

Well, the compiler is smart enough to remind us that we need to consider if a specific user should have access to the data that you are returning from the function.

In addition, to check if a user has permissions to a specific field, we can use the hasFieldAccess function. There are other functions we can use as well such as hasMenuItemAccess, hasSecurityKeyAccess amd hasTableAccess.

An example is shown below:

//BP Deviation Documented

display vatNumJournal TaxExemptNum()

{

    if(!hasFieldAccess(tablenum(SalesTable), fieldnum(SalesTable, VatNum)))

        throw error("@SYS57330");

    if (SalesTable.VATNum)

        return SalesTable.VATNum;

    else

        return '';

}

The BP Deviation Documented comment line just above the function is to tell the compiler we have addressed the issue.
