During the cancellation of invoices and debit notes, the sales lines are created initially based on sales invoice as reverse transaction. All sales line related dimensions is copied from origin invoice lines during this creation. If WM and other inventory transaction related process are used, the inventory dimensions like location and license plate cannot be assigned to the respective sales lines.

In order to manage this process either the lines location and license plate (Dummy license plate will be created in order to use within both alternatives) should be filled manually or the related dimension should be assigned as default during the creation of sales line. If there are a lot of lines to be cancelled, then this part should be customized during the creation of cancellation related reverse sales line transactions. 

The requirement for this topic is to automatize update as default value for location and license plate which will be created blank based on original invoice lines in standard. If there are too many invoice lines at the invoice it is not manageable to update all manually.
