A: When you want a product to disappear at a certain time from the acquisition or sale documents, but still be capable of being engaged in document rectification (of any kind), it is recommended to check the Purchased and Sold checkboxes that appear in the Product window. From the moment you de-select the Purchased checkbox, that product will stop appearing in the list of products available for procurement documents. From the moment you de-select the Sold checkbox, that product will stop appearing in the list of products available for sale documents.
However, the cancellation or reverse procedures will still function correctly and thoroughly.
Note: If you deactivate the product bt de-selecting the Active checkbox, you will stop being able to use the product in any way!
A: starting with v14.06 was added a new report in menu Product Setup / Check Products Accounts Report, which ran for a category of products will list only those items that do not comply with established accounts at category level. Just checked the product asset, product expense and product revenue accounts from the product definition versus the category definition, for indicated accounting scheme. The report can be run without specifying a category, in which case you can use the parameter "category exempt". This test is useful for catching all categories except the category that contains the "Expenses" that is usually heterogeneous conceptually items and accounting expense accounts.
