What you have to make a join on PO_DISTRIBUTIONS_ALL (REQ_DISTRIBUTION_ID) and PO_REQ_DISTRIBUTIONS_ALL (DISTRIBUTION_ID) to see if there is a PO for the req.
--You need to find table which hold PO Approval path…

10] To know the link to GL_JE_LINES table for purchasing accrual and budgetary control actions..The budgetary (encumbrance) and accrual actions in the purchasing module generate records that will be imported into GL for the corresponding accrual and budgetary journals.
The following reference fields are used to capture and keep PO information in the GL_JE_LINES table.
These reference fields are populated when the Journal source (JE_SOURCE in GL_JE_HEADERS) isPurchasing.
Budgetary Records from PO (These include reservations, reversals and cancellations):
REFERENCE_1- Source (PO or REQ)
REFERENCE_2- PO Header ID or Requisition Header ID (from po_headers_all.po_header_id orpo_requisition_headers_all.requisition_header_id)
REFERENCE_3- Distribution ID (from po_distributions_all.po_distribution_id orpo_req_distributions_all.distribution_id)
REFERENCE_4- Purchase Order or Requisition number (from po_headers_all.segment1 orpo_requisition_headers_all.segment1)
REFERENCE_5- (Autocreated Purchase Orders only) Backing requisition number (from po_requisition_headers_all.segment1)
Accrual Records from PO:
REFERENCE_1- Source (PO)
REFERENCE_2- PO Header ID (from po_headers_all.po_header_id)
REFERENCE_3- Distribution ID (from po_distributions_all.po_distribution_id
REFERENCE_4- Purchase Order number (from po_headers_all.segment1)
REFERENCE_5- (ON LINE ACCRUALS ONLY) Receiving Transaction ID (from rcv_receiving_sub_ledger.rcv_transaction_id)
Take a note for Period end accruals, the REFERENCE_5 column is not used.

12] There are different authorization_status can a requisition have.Approved
Cancelled
In Process
Incomplete
Pre-Approved
Rejected
and you should note: When we finally close the requisition from Requisition Summary form the authorization_status of the requisition does not change. Instead it’s closed_code becomes ‘FINALLY CLOSED’.
13] A standard Quotations one that you can tie back to a PO.Navigate to RFQ -> Auto create -> enter a PO and reference it back.14] To debug for a PO , where should I start.Thats is possible, your PO get stuck somewhere, so what you have to do is to analyze which stage it stucked.Get po_header_id first and run each query and then analyze the data.For better understanding this is splited into 5 major stages.
Stage 1: PO Creation :
PO_HEADERS_ALL
select po_header_id from po_headers_all where segment1 =;
select * from po_headers_all where po_header_id =;
po_lines_all
select * from po_lines_all where po_header_id =;
po_line_locations_all
select * from po_line_locations_all where po_header_id =;
po_distributions_all
select * from po_distributions_all where po_header_id =;
po_releases_all
SELECT * FROM po_releases_all WHERE po_header_id =;
Stage 2: Once PO is received data is moved to respective receving tables and inventory tables
RCV_SHIPMENT_HEADERS
select * from rcv_shipment_headers where shipment_header_id in(select shipment_header_id from rcv_shipment_lineswhere po_header_id =);
RCV_SHIPMENT_LINES
select * from rcv_shipment_lines where po_header_id =;
RCV_TRANSACTIONS
select * from rcv_transactions where po_header_id =;
RCV_ACCOUNTING_EVENTS
SELECT * FROM rcv_Accounting_Events WHERE rcv_transaction_id IN(select transaction_id from rcv_transactionswhere po_header_id =);
RCV_RECEIVING_SUB_LEDGER
select * from rcv_receiving_sub_ledger where rcv_transaction_id in (select transaction_id from rcv_transactions where po_header_id =);
RCV_SUB_LEDGER_DETAILS
select * from rcv_sub_ledger_detailswhere rcv_transaction_id in (select transaction_id from rcv_transactions where po_header_id =);
MTL_MATERIAL_TRANSACTIONS
select * from mtl_material_transactions where transaction_source_id =;
MTL_TRANSACTION_ACCOUNTS
select * from mtl_transaction_accounts where transaction_id in ( select transaction_id from mtl_material_transactions where transaction_source_id = =);
Stage 3: Invoicing details
AP_INVOICE_DISTRIBUTIONS_ALL
select * from ap_invoice_distributions_all where po_distribution_id in ( select po_distribution_id from po_distributions_all where po_header_id =);
AP_INVOICES_ALL
select * from ap_invoices_all where invoice_id in(select invoice_id from ap_invoice_distributions_all where po_distribution_id in( select po_distribution_id from po_distributions_all where po_header_id =));
Stage 4 : Many Time there is tie up with Project related PO
PA_EXPENDITURE_ITEMS_ALL
select * from pa_expenditure_items_all peia where peia.orig_transaction_reference in( select to_char(transaction_id) from mtl_material_transactionswhere transaction_source_id = );
Stage 5 : General Ledger
Prompt 17. GL_BC_PACKETS ..This is for encumbrances
SELECT * FROM gl_bc_packets WHERE reference2 IN (’‘);
