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.

Languages in AX 2009 - Using a the LanguageTable form for Lookup building- AX 2009

Today I had a requirement to only show the following language across the whole application:
  • en-us
  • fr
  • it
At first I thought to create a custom lookup method as I did for another requirement last month (http://axwonders.blogspot.com/2011/03/filter-activity-form-contact-to-only.html), but then I thought .. Oh my .. this would mean to add a lookup method to several forms across the application, and what about if I need to change something in the future? It was a fact that the scalability of this change will be an issue.

Because the requirement said "Across the application" I decided to modify the LanguageTable form to be shown as a lookup in every instance of the LanguageID across the application.

The following are the steps I took:
