Hi there,

I have a sitefinity site on development, It already have a database with older orders and customers. I want to reset the order number to a smaller number than[eg: 200] the one in the sf_ec_next_order_number [eg:5200]. and the existing db contains an order number 200. I dont want to keep the existing orders. they can be deleted. How to reset the starting sequence of sitefinity ecommerce order number in this situation.

Thanks
