Capturing Project Cost Through Work Centre

Hi Techies,

In the current situation my client use the work centre in the routing of a product for capturing the cost of the project they spent for that respective product. Now they want to have the same kind of requirement in SAP. I know if we use Project System we can capture the cost of the project. But right now we don have Project system in scope. So its not possible to use project system. In that case wat would be best suggestion from SAP point of view for this requirement. Is there any standard practice to capture project cost for a product without having project system.

Could you please advice me on this

Thanking you in advance.

Regards,

Kris.S
