When you want to pick items for the BOM picking process.
Finding a BOM picking list and click on the button "Attach to Cart" opens a new page with carts.
The newly opened page then select the cart you want to use and click on the button "Attach to Cart" marked in red on below image. Once the cart is attached, the picking list is opened and you can begin loading items onto the cart.
If Picking List is Already Attached to a Cart
If you select a picking list and the button "Attach to Cart" is not visible, illustrated on below image.
Delete Reference
This means that the picking list is already attached to a cart. To resolve this you need to open the carts menu and begin using the cart that contains your picklist or you delete the reference to the picking list. Marked in red on below image, you can delete the reference.
