Hi Jeffrey
I guess you are asking about trading material.
As per my knowledge we can achieve with below process.
1. Create a FERT material MM01.
2. Maintain BOM with packing materials CS01.
3. Create work center and assign assign the activity types CR01.
4. Create Routing and assign the work center in Routing CA01.
5. Maintain the activity price in KP26.
6. Run the Cost Run in CK40N
7. Create Production Order for 5Kg CO01.
8. Do the Goods Issue to the Production Order with 261 Mov Type in MB1A/MIGO.
9. Do the confirmation in CO11N.
10. Do the Goods Receipt in MB31/MIGO.
11. Change the Order to TECO.
12. Do the Settlement in KO88.
By doing this process you can capture the Cost of Packing Materials and Work Center Activities.
