Use the Link Job command to link materials in Production Control to pre-purchased advanced bill materials. Tekla EPM uses reference numbers to match the materials across modules. Any unlinked materials, such as loose pieces, will be loaded into a requisition or a purchase order to be purchased.

1. In the Production Control dialog box, click the Production Control ribbon tab.
2. On the menu, select Purchasing > Link Job.
3. To limit which materials are linked, in the Link Filters dialog box, select a filter type in the Type list, and click Select.
4. In the Filter dialog box, do one of the following depending on the filter type:
   1. Click the arrow buttons to move the items whose heat documents you want to view to the Included list.
   2. Type the maximum and minimum values for the items whose heat documents you want to view.
5. Click OK.
6. If necessary, select the If updating a cut list item, exclude from being cut check box.

   By selecting the check box, you can ensure that Tekla EPM does not invalidate the entire cut list when an item in the cut list is updated. Updated items will be saved in the inventory to be processed later.

7. Click Link.
8. In the Link Items dialog box, click if you want to load material information to a requisition or a purchase order.
9. Click the desired requisition or purchase order.
10. Click OK to load the materials.
11. Click OK to close the Link Items dialog box.
