This forum is to discuss different features/issues of Oracle Financials modules ( GL - General Ledger, AP - Accounts Payable, AR - Accounts Receivable, FA - Fixed Assets & CM - Cash Management ).
I suggest to use any tools can transfer the data from PDF to excel sheet then you can use data loader to upload the data to accounting segment in your set of book.
As suggested by expert Gurus, first convert pdf to excel, if not just copy and paste to excel, then down load data loader (free software) best to use oracle application.
