Populate expenditure organization in Projects running Cost Collection Manager and PRC: Transaction I

 Which field in the pa_transaction_interface_all table is responsible for the expenditure organization name population in Projects. I am trying to use a custom logic through the Cost Collector Extension hook to populate organization_id, organization name, override organization etc. in the pa_transaction_interface_all  for the further import. Nothing works for the expenditure org to loadinto Projects (Project Accounting). Any ideas? Thanks.
