Material To be Valuated in Project System

Question

Hi All,
We are implementing PS,MM,SD,FI &CO for a companay which works essentially on engineer to order scenario and using vlauated projec stock & actvity account assigned networks
Inhouse production is through typical assembly processing process - Where input & output materials are transferred through BOM PS Transfer from WBS BOM.
Input materials are issued to activity; work performed by work centers are entered by confirmation; at completion of work out put materials is 'Received from activity'. Both material issue and receipt are done wrt reservation.
When this is done, as per standard process, the cost addition (and hence value addition) is to activity and thereby to WBS element. The output material is not valuated. All the cost(or values) become project value which will reflect in WIP calculation. WIP is calculated as month end process.
At month end if the company wants to know the current asset from project and relevant stocks:
= WIP of project + Inventory value of the mmaterials.
Pl. note that only input materials i.e. raw materials and Bought out materials will have inventory value; the output material will not have any value.
The process is alright and I think we are alos complying to Accounting stanadard for project system - directive from Institute of Chartered accounts - India.
This process was first aceeptable to customer; but now they say -  the out put materials should be valuated. So that, when inventory value is taken - it is RM+BO and valuated semifinished +valuaed finished materials
One big reason they say is that they have to show inventory value to the Banks.
Now I need clarification in following points
1. How to valuate the out put material when working only with project system. (apart from using user exit )
2. If this is done, the project cost/WIP calculations will show ups amd downs - as goods receipt with valuated value will be with sign - this will reduced the cost. This will cause variuos problems - almost no standard SAP PS cost report will reflect the reality - WIP can not go up and down...This is illogical.
3. Have you faced similar situation in implementation - that - Banks can not be conviced about this PSway of WIP calculation? Taking into consideration that project implementation is in India - an experienced reply can be very helpful
Thanks and regards

Dear Pradeep,
When we work with network/activity/wbs element, Finished material is assigned to activity with sign. This means GR can be done. Technically system treats lke by-product. This material will not be valuated with in put costs...since there is no logic...For our convention, one WBS element, one network or one activity can be used to book all related costs..but still GR will happen with valuation as per valuation variant in NW only. This is quite logical and correct.
So...customer wants to know the cost of manufacturing a complex project assembly..then process under one WBS element..cost accumuated at that WBS element is cost of mfg. I have kept such finihed material std price at Rs.1. (Ideally it should be '0'.). Meaning material will not valuated.
Now if customer wants to knwo the cost ...look at WBs element
If needed, you can do unit costing and update the value in a suitable field in material master.
Therefore, I have kept all the semifinished/finished material std price at Rs.1.
This way..std functions of PS like RA, costforecasting are work properly.
For WIP calculation, this is of standard method and WIP will be current asset of company..this will be acceptable to Banks...one concern I had..cross checked with a Banker.
Another issue was sub-contracting. In India during S/C..we have Delivery challan and legal requirement of excise. We developed a program integrating dc, excise challan, transfer posting, goods issue against reservation and mateials assigned in activity. For user it will appear as one transcation, and system will propmt/list appropriate excise challan No. based on dc no & material as input...(I hope i remember right).
Again here GR of seni/finished naterial was atRs.1. since Service cosst, matarial issue cost get booked at activty.
Thanks and regards
