I have been trying sync my sales with quickbooks and I am getting the following error:
Error:6000: [A business validation error has occurred while processing your request, Business Validation Error: You are not allowed to modify the quantity of an inactive inventory item.]
I have noticed both order that are giving this error have items that were the last units in stock when the sale was made.
I suspect it has something to do with the way I have mult-inventory set up for those items., but I am having difficulty figuring out where is the error. I would appreciate some pointers.
