How to display an image according to test result OK or Not Ok using macro of AX

To do so you must use the macro : resAppl from the AOT and this following method:

/// <summary>
/// A display method that converts the test result to an image ID.
/// </summary>
/// <returns>
/// Image_Ok if the test passed; otherwise, Image_NotOk
/// </returns>

//BP Deviation Documented

display ProjTestImage displayResultImage()
{
    #resAppl
    ;

    //Check if user has security access
    if(!hasFieldAccess(tablenum(ThyProjForcasTable),
                       fieldnum(ThyProjForcasTable, NoYesId),
                       AccessType::View))
    {
        return -1;
    }

    if(this.NoYesId == Noyes::Yes)
        return #Image_Ok;

    return #Image_NotOk;
}

See example in the form InventQualityOrderTable in the AOT.
