We are implementing SAP Project Systems module for our client as part of ECC 6.0 global roll out and we are looking for a solution to meet the with following business scenario:
The sales company (CC : US01) receives a purchase order for large project from an external customer. The sales company creates a sales order in SAP with delivering plant that belongs to another legal entity ( CC : US02 and plant : USP2) that has the main engg.facility . Two projects ( WBS elements ) are created for the sales company and engg.company . WBS element 1 element is used to drive milestone billing for the external customer and WBS2 element is created to post revenues and costs for the main engg.company
( CC :US02). The main engg.company plant ( USP2) has to procure sub structures from another legal entity in the company ( CC :US03 and plant :USP3) . We are creating an inter company stock transport order from USP2 ( main engg.company ) on plant USP3. In standard SAP , the stock transport order carries WBS2 that belongs to purchasing plant. But the business requirement is to have their own WBS element for USP3 plant to capture costs and revenues. What's the best of way of meeting the above business requirement either through standard SAP configuraion or some user exists with manual process.
I'd appreciate any suggestions or ideas from the experts !
