COGS of goods work flow

 Hi,

We are trying to customize the Cost of goods work flow. Instead of picking the COGS from Item we want to build our own procedure

We have 7 segment segments in GL.

We will take the firsth segment (Branch), second segment (Natural Segment) from cogs account from mtl_system_items and the third segment from one of the descriptive flex fields say profit center.

The work flow we are using is Order Line, and OM: Generate Cost of 

Could some one reply, how to go about with this or which procedure to be modified using which function.

Should you require more information please revert.
