I need help for finding tables relating fields INVOICE_ID, NOTIFICATION_ID and APPROVAL_STATUS or WFAPPROVAL_STATUS. I have searched a lot but has been unable to find any table containing all the above mentioned fields. I found the table WF_NOTIFICATIONS for INVOICE_ID, however have been unable to find the latest tables with INVOICE_ID and APPROVAL_STATUS as fields.
All the tables having this combination are either very old tables which are not used anymore or doesnt give the required data. Please let me know where am i going wrong. Once i get the required tables, i need to join the tables to get the required data with the imp fields. Also, the values of WFAPPROVAL_STATUS are not very clear to me. I need values for it as APPROVED, REJECTED AND INITIATED.
