Tried like this :
ShopGroupID
ShopGroupName
ShopGroupID
ShopGroupParentID
ShopGroupNumber
ShopGroupSort
ShopGroupSort
ShopGroupID
And since all values equivalent to manually created group values, maybe it is because there was already groups created in dynamicweb ecom module.
Question is, is there is other way to do it simply ? If not what could be wrong with this try ? How to delete default standard auto-incremented Group id value ? For example even if there is no groups in ecom, and i create one, its id will be Group35, how to reset that to Group1 or etc ? Is this could cause import problem ?
