Create a return, restock and credit without a linked sales order VEND INTEGRATION

In a retail businesses you quite often need to process a return, but the original sales transaction may not be located within system. Currently this can only be handled by creating a standalone credit and then seperately creating a stock adjustment (Two seperate processes that are not linked in the system).  Given the volume of these instances occuring and difficulty to identify, it would be more stremlined and better practice to allow a inventory credit and restock to be created simultaneously that does not have to be linked to an original sale.  This functionality is now provided for within  Dear POS so I am requesting the Vend and Dear Integration to be updated to cater for this regularly occuring scenario.

Currently No restock is created and a negative Additional Charge is generated which creates substantial integrity and tracing issues.
