How can a statement be generated?

how can I generate Statement to the supplier ? and we are working on commissions
As I have the latest with the different interface

Invoice with selling price in custom field and commission component in Manager’s item price. You can use Manager’s field calculator to do the sum.

Do you mean issuing the Statement Of Account to a supplier?

yes, which includes commission, documentation charges and other shipping expenses

@Hassan_Hafeez, your post does not make sense. Why are you documenting these items to a supplier? The supplier should be sending you a sales invoice listing these items.

Perhaps you should describe your situation more completely.
