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.
