A return operation can be recorded by selecting Sales Return Dispatch or Invoice type, or it can be performed over the related dispatch or invoice directly. To do the latter, you use "Take Back" option located on the right click menu of Sales Invoices, Sales Dispatches and Service Sales Invoices browsers.
When a return operation is performed, input/output cost of the dispatch or invoice is transferred to the return slip. Return quantities and slip connections of the slip are generated. The "Take Back" option is located on the right click menu of Retail Sales Dispatch, Wholesale Dispatch and Consignment Dispatch in Approved, Under Way, Delivered statuses and Retail Sales Invoice and Wholesale Invoice in Approved and G/L Approved statuses. 
Lines including quantity values greater than zero are transferred to the return slip of the relevant slip type by Take Back option. The dispatch/invoice types which are generated in return transactions performed over the dispatch/invoice browsers are as follows:

The promotion materials and net amount are transferred in return transactions according to the parameter values specified in System Settings module > Administration Default Values and Parameters > Sales Management window.
