There are a number of parameters that are of importance when processing returns.

769	Enables you to define whether returned articles must be added to the original stock batch	Value 1 means they will not be added, in which case a new stock batch is created. Value 2 means they will be added.
1235	Makes it possible for you to make sure that return lines do not appear on a separate credit invoice, but that these lines are included with the first “normal” plant invoice. These return lines will then be visible on the invoice as a negative quantity.	If this parameter is set to value: 1, then this will apply for all return lines. When you process returns, it will not be possible to create a credit invoice. The default value of this parameter is: 0 so that credit invoices for the return lines can be created.
1219	Enables you to define whether returned articles must be booked to the default location	value: 1= default or to the location from which the articles originally came (value: 2). This parameter is only used if the WinTree module 66, Location management, is active.
1522	Enables you to define whether, in the case that the stock has to be increased, under which article (plant name – plant quality combination) the returned articles must be booked.	Value: 1 means book as article from the sales line. Value 2 means book as an article as was already allocated.
1536	Enables you to define what happens if a delivery line (that has not yet been invoiced) is returned.	Value 1 removes the returned quantity from the delivery and lowers the order quantity (this value is the default). Value 2 makes sure that the delivery line continues to exist and can be placed on a credit invoice.

All parameters can be defined via WinTree Tools. Parameters 1219, 1235 and 1522 can also be defined via a checkbox in the Properties window of the “Process returns” window.

If WinTree module 66, Location management is also active, a default return location must be defined in the settings menu. This location is selected via the menu File -> Settings -> Tab page "General". Select one of the locations from the basic data via the drop-down list.

When credit invoices are created, a separate header and footer text is used. This header and footer text can be entered via the basic info. There is a separate type 'Credit invoice' available for this. Remember to specify the entered text as Default text.
