Topic: Stop auto updating standard cost

For me the standard cost makes changes abnormal, is there any way to prevent making changes in the system instead of doing auto calculations.

Re: Stop auto updating standard cost

That may need customization.
You may need to create sys pref in company setup like std_cost.
Once check you can apply condition to not call update_average_material_costs function defined in purchasing/includes/db/

One more controlled average costing can be just to call this function when a new item is purchased.
