add existing inventory item to a matrix

AI generated answer (using internal Slack threads):

To add an existing inventory item to a matrix, you would need to create a new Matrix Item. Unfortunately, NetSuite does not allow you to convert an existing inventory item into a Matrix Item directly. Matrix items in NetSuite are used to handle items that come in different variations, such as size or color. When you create a matrix item, you first create a parent item that describes the basic characteristics of the items in the matrix. You then add child items that represent each variation. Here are the steps to create a Matrix Item: 1. Navigate to Lists > Accounting > Items > New. 2. Select the type of item you want to create. 3. In the New Item page, check the 'Matrix Item' box. 4. Fill in the necessary fields for the parent item. 5. In the Matrix subtab, select the options for the child items. 6. Click 'Save & Add Another' to add each child item. Remember, each child item in the matrix can have its own SKU, price, and other attributes. Please note that once an item is set as a Matrix Item, it cannot be changed back to a regular item. Also, you cannot convert most item types into other item types, the only real supported one is non-inventory into inventory. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
