This seems impossible (V8 Saas): the search returns no results.
Any reason for this impossible search?
Without the cost information, all accounting leads to erroneous entries. And there are a lot of reasons for not being able to have costs from the beginning of the creation of a product.
Is there is another way to audit the costing data?
How are you currently searching for this? Advanced search for Cost = 0.0 seems to work for me.
Searching for "Prix de revient" works for any other values than 0.00! As if 0 is not a number. I made a final test setting a product with a cost =0.00>>the search returned nil; then changing the said cost to 0.01>>the product was selected. This remains an issue for me because our database is made of several thousands of products; thus hard to monitor. Thanks for your comment.
