Cost Component break up for Sub-contracting cost in CK11N

Hi,

For the new business requirement, We've created new cost components,, and are able to view successfully in CK11N with origin group settings. Now, we want to break the sub contracting cost and see it spread across different cost components as maintained in Purchase info records, in other words, in the same way as other material cost. Since, standard SAP doesn't provide break up option of for subcontracting, we are trying to achieve it through development.

Now, we are able to see the sub contracting cost splitting across it's components in CK11N, however, in itemization view, it still goes to the same cost element.

Que- How do we break up sub-con.cost to its respective cost elements?

Thanks,

Nirav
