HTML Parts Requirement - No Stocking Location found to display on map.

We're trying to do parts requirement transaction in HTML parts requirement form but we can not use availability function same as form parts requirement screen. First  we clicked search parts button and then click show on map button for checking

warehouse availability but we got 'No Stocking Location found to display on map' error. Do you have any idea how can we check on-hand availability in HTML parts requirements?

Thanks,

Burak
