Further Information > Create Should Cost Calculation

Step 2: Insert Assembly

1. Select the should cost calculation in the Structure view.

2. In the ribbon, click on Edit > Insert > Assembly (Piece).

   An assembly is inserted into the calculation structure.

3. In the Details view (Calculation view schema ), select the manufacturing valuation Calculate Cable Harness.

   The process is automatically renamed to "Cable Harness".

   A new group Manufacturing Valuation appears with sub-groups.

 

Step 3: Insert Material

This cost model requires using materials with quantity type "Length" and material classification "Cable/Wire". Thus you can administer further parameters at the materials, such as:
