Purchase Expenses forming part of OPM GL Expense Allocation

Hi All,

Did any one created , any  setup  where Expenses booked from Purchase Module are forming part of  OPM GL Expense Allocation ?

In the above, does it required to post the Purchase Module data to General Ledger first, if so is it required to run other processes like Actual Cost process and Cost Update prior to doing so. ?

The catch  is.. if  it is required to  post the Purchase Module data to General ledger, you are executing the Create Accounting in final mode , what is the impact of .. Profile Option 'GMF: Check If Costs Are Frozen  ?

And also,  executing the GMF Re-create Layers,  after posting  any data to General Ledger is not feasible . how to handle this as well..
