A Item Variant is a version of an Item, such as differing sizes or differing colors (like a blue t-shirt in size small rather then just a t-shirt).
Without Item variants, you would have to treat the small, medium and large versions of a t-shirt as three separate Items;
Item variants let you treat the small, medium and large versions of a t-shirt as variations of the one Item 't-shirt'.
1. Using Item Variants
Variants can be based on two things:
- Item Attributes
2. Item Variants Based on Item Attributes
To use Item Variants in ERPNext, create an Item and check 'Has Variants'.
The Item shall then be referred to as a so called 'Template'. Such a Template is not identical to a regular 'Item' any longer. For example it (the Template) can not be used directly in any Transactions (Sales Order, Delivery Note, Purchase Invoice) itself. Only the Variants of an Item (blue t-shirt in size small) can be practically used in such. Therefore it would be ideal to decide whether an item 'Has Variants' or not directly when creating it.
On selecting 'Has Variants' a table shall appear. Specify the variant attributes for the Item in the table. In case the attribute has Numeric Values, you can specify the range and increment values here.
Note: You cannot make Transactions against a 'Template'
To create 'Item Variants' against a 'Template' select 'Make Variants'.
To learn more about setting Attributes Master check Item Attributes
3. Item Variants Based on Manufacturers
To setup variants based on Manufacturers, in your Item template, set "Variants Based On" as "Manufacturers"
When you make a new Variant, the system will prompt you to select a Manufacturer. You can also optionally put in a Manufacturer Part Number
The naming of the variant will be the name (ID) of the template Item with a number suffix. e.g. "ITEM000" will have variant "ITEM000-1"
4. Update Item Variants Based on Template
To update the value in the variants items from the template item, select the respective fields first in the Item Variant Settings page. After that system will update the value of that fields in the variants if that values has been changed in the template item.
To set the fields Goto Stock > Items and Pricing > Item Variant Settings.
