I guess i knew how , i need to make an offer buy 2 get 1 free in all stores and i figured that to do that i need to open each item and choose the discount scheme to do that . That is not practical actually as i need to do that to all the items in the store .
after searching the web i figured that need to make and sql statement like this
Update Group of Items by Department
Open Store Operations Administrator.
Open a Query window by clicking Query then New.
In the New Query window, run the following SQL statement:
UPDATE Item SET QuantityDiscountID = (SELECT ID FROM QuantityDiscount WHERE Description = '<DiscountName>')
WHERE DepartmentID IN (SELECT ID FROM Department WHERE Name = '<DepartmentName>')
Note:
In the New Query window, paste this SQL statement by pressing CTRL+V.
Replace <DiscountName> with your new discount's name and <DepartmentName> with the name of the department where the items to be updated belongs to.
Press F5 to run the query.
Update Group of Items by Category
Open Store Operations Administrator.
Open a Query window by clicking Query then New.
In the New Query window, run the following SQL statement:
UPDATE Item SET QuantityDiscountID = (SELECT ID FROM QuantityDiscount WHERE Description = '<DiscountName>')
WHERE CategoryID IN (SELECT ID FROM Category WHERE NAME = '<CategoryName>')
Note:
In the New Query window, paste this SQL statement by pressing CTRL+V. You cannot right-click in the New Query window to paste text.
Replace <DiscountName> with your new discount's name and <CategoryName> with the name of the category where the items to be updated belongs to.
and after that i need t to run the worksheets .
Thank you for your reply .
