Modify/create a production structure
A production structure is a KIT structure with modification for a specific production. This is useful in situation where the customer needs a product with certain modification, such as different color or using different parts.
To create a production structure, enter the Production Work Order (PWO) containing the KIT you wish to modify.

Click the green KitId icon to the right in the window.
The view will change to the KITDOC document. Here you can see all the operations and parts in this structure.

Click the Kit Designer folder at the top to modify the kit.
Use the drag & drop functionality to modify the structure by need. Use the Insert part/Replace part button to either add or replace parts. Use the Switch to Operation icon in the upper right corner to switch to operations if needed.
After you have made your modifications, click the Activate version icon.
Choose if you want to keep the structure on hold, or release it for production.
