PO item accrual for logistics overhead collected in CO

Dear all,

I do not feel quite competent enough to tackle the following problem:

We have a cost centre: OH logistics. And we feel that these costs should become part of the inventory valuation based on an estimated amount per PO line item.

Therefore we want to set an accrual for these costs in the PO item details conditions so that at goods receipt they are in the inventory valuation.

How do we set up the FI side?

At goods receipt: The stock account goes +, GR/IR account will -. Do we have to define a separate account for these logistics costs to - or should I use the sale GR/IR clearing? (no invoice will come in for the logistics accrual off course)

At the time of goods issue the stock account - but to which account? (both if we create a G/L account for logistics?)

What do we do with the costs collected in the cost center.How do we analyse the costs on stock for these accruals?

Any help will be much appreciated.

Regards,

Michaë
