When creating a new Product in CheckIn, add the Item Name, Manufacturer, Product Code, Preferred Supplier and Supplier Code (SKU), as well as costs and pricing. Remember also to add the Department/Class -- CheckIn will warn you of the consequences for saving a Product without a Department/Class. Once finished, click the "Save" button at the top to save the record.
You have the option to add multiple Suppliers for a Product. When a Product is added to a PO for each Supplier, it will use the Supplier Code specific to that Supplier. While you can have and use multiple Suppliers for a Product, you can select only one Preferred Supplier, and this will be the information you'll see on the Product Card.
Multiple options are available under the "Gear" menu at the bottom right, allowing you to create Adjustments and Merge Products. "Maintenance Check" may be useful in resolving inventory issues by updating records.
If you see the "DUPE!" label on the Product Code, this means that there is another Product with the same Product Code. Clicking on the label will open a list of products with the same Product Code, including any Products Flagged as Inactive. To resolve the issue, you'll need to change the Product Code.
