I need to Assign More than one group to supplier, as the same supplier may have more than product categories
This is not possible with the current ERPNext configuration. You can only assign one supplier group to a supplier. But you can add custom field/s for this to allow multiple supplier group for one supplier.
Thanks for reply,
I set tags for supplier, to achieve my goal,
But i have another problem.
I cannot add custom field in project form,
when i press update it’s not updating, although customization of all forms is working fine
