How to map WBS structure in MTO process?

Hi friends,

Can we have different billing element WBS and account assigned WBS?

Suppose the WBS structure is :

1st level  : XXX-01       (Billing element)

2nd level : XXX-01-01   (Account assigned)

Billing element wbs XXX-01 assigned to SO and account assigned wbs XXX-01-01 assigned to production order. All the procurement done wrt wbs XXX-01-01.

Now during GR of FG in production order, FG will come in project inventory with wbs assigned XXX-01-01. But the wbs assigned in SO is XXX-01, so when we will do the outbound delivery, it will check the FG inventory in wbs XXX-01 but the FG lies in wbs XXX-01-01.

Please correct me where i am going wrong.

With regards,

BBR
