1. Open Inventory Management, Main menu, Item Maintenance
2. Select the Item Code
3. Click More (or the drop-down chevron button at the top right)
4. Select Alias to open the Alias Item Maintenance window 
5. Enter Alias Item No. to create a new one for the Item Code (or select an existing alias to edit the Description , or click Delete to remove an alias).
6. Select a Type (choose one of three):
• Select General to create a general alias usable in data entry for customers or vendors
• Select Customer for customer type aliases. This option is available only if Accounts Receivable is installed.
• Select the Customer No. that the alias will be created for.
• Select Vendor for vendor type aliases. This option is available only if Accounts Payable is installed.
• Select the Vendor No. that the alias will be created for.
• Note: This does not create a Vendor Item Code for the vendor. For more information, see the Related Resource section below.
7. Enter a Description for the Alias Item Number
8. Click Accept

Note: The steps above will create a record in the IM_AliasItem.m4t file. Creating an Alias item Number of Vendor type does not create a Vendor Item Code for the vendor. However, if in Alias Item Maintenance, you select and Delete an Alias Item Number of Vendor type that was initially created in Vendor Item Maintenance, then the Vendor Item Code field value will be cleared (but the item vendor record will still remain).
