wholesale price bulk editing

when I us program to set all product wholesale price type as Percentage, if I only set discount 10%, without setting wholesale price. Then product page can not be opened.

And if I only change product’s normal price, wholesale price does not change accordingly.
I must always go to product editing page to change price or discount percentage.
It is too slow to edit several thousands of products manually one by one.

Please fix the error. Your plugin should count wholesale price automatically when discount percentage is set.
