In Zentail, a Kit SKU is a SKU that either has multiple units of an underlying SKU (aka "Pack") or multiple underlying SKUs (aka "Bundle).
Here's how to create a Kit SKU from scratch:
On the Catalog page => Click the blue 'pencil' icon button on the bottom right of the page.
Enter your SKU => Click the blue 'check' button on the bottom right to save.
Click the 3-dot icon at the top of the left sidebar => Click "Make Kit"
Enter the SKU you want to include into the "SKU" field => Click "SEARCH" button
Repeat until all underlying SKUs are included.
[If the Kit will have multiple units per underlying SKU] Click the '+' button for the product in the "Kit Contents" section until it shows the # of units desired.
Click the "CREATE" button
Here's how to turn an existing SKU into a Kit:
Find the SKU in the Catalog table => Click on it.
Click the 3-dot icon at the top of the left sidebar => Click "Make Kit"
Enter the SKU you want to include into the "SKU" field => Click "SEARCH" button
Repeat until all underlying SKUs are included.
[If the Kit will have multiple units per underlying SKU] Click the '+' button for the product in the "Kit Contents" section until it shows the # of units desired.
Click the "CREATE" button
