Using Transaction Cost Extension - CSTPACHK - to calculate cost

Question

We want to use the transaction costing extension (CSTPACHK) to modify the cost of items. The procedure we want to modify is 'actual_cost_hook'. The documentation available, like the Costing User Guide, specify that we have to include our custom code and then return a 1 from the package to tell the Cost Manager to use the custom code instead of the standard code.
What I don't understand, and what is not clear in any of the documentation, is what to do after we determined the custom cost. It is not a parameter in the procedure that we can send back to the standard process. Do we have to insert or update a table with the newly generated code? The documentation seems to suggest that we update the 'mtl_cst_actual_cost_details' table. But my concern is that it is a standard table and should therefore not be updated.
What is the correct way of sending the newly generated code back to the standard process?
Thank you,

Hi Elisca,
If you observe carefully structure of CSTPACHK, procedure actual_cost_hook is function called from Oracle standard package CSTPAVCP which use to process all material transactions.
Now for your situation you should try to return calculated cost in fucntion actual_cost_hook thats enough.
Remaining things system will take care.
So dont think to update any standard tables, whatever function re turns system should update that cost.
Let me know if you have any concern.
