Hello Sid,
Its little difficult to provide the transaction work flow completely. But here is the brief information :
1)Timesheet transacition - Post Timesheet - IMP_TRANSACTIONIMPORT table - shown as new transactions under invalid transactions.
Via XOG/Scheduler - directly into IMP_TRANSACTIONIMPORT table.
2)If Project/resource financially enabled, Post transactions to financials will move the transactions from IMP_TRANSACTIONIMPORT to PPA_TRANSCONTROL and PPA_TRANSACTION_VALUES if timesheet and project fulfil all requirements.
3)Transaction Entry function - Directly to to PPA_TRANSCONTROL and PPA_TRANSACTION_VALUES.
4)POST to WIP - Moves data from PPA_TRANSCONTROL and PPA_TRANSACTION_VALUES to PPA_WIP and PPA_WIP_VALUES. (Future transactions will be left back)
5)Import financial actuals - Copies transaction data from PPA_WIP and PPA_WIP_VALUES to assignments.
Hope this information helps.
