Dears,

Requirement

In mobile I am trying to hide user_def16 and user_def17 from part_usage table and bin_id from stock_bin table based on the access group (which is ‘ELUX_US’) .

var taskId = getCurrentKeys("task", "task_id");
var partUsage=getCurrentKeys
var binID=getCurrentKeys
var AccessGroup = getDBValue(stringFormat("SELECT access_group FROM task WHERE task_id = {0}");
if (AccessGroup == 'ELUX_US') 
{    
    setControlVisibility('part_usage','user_def16',true);
    setControlVisibility('part_usage','user_def17',true);
    setControlVisibility('stock_bin','bin_id',true);    
}           
else
{
    setControlVisibility('part_usage','user_def16',false);
    setControlVisibility('part_usage','user_def17',false);
    setControlVisibility('stock_bin','bin_id',false);
    
}
