Data Stuck in Purchase Receipts :

We Can See some scenarios like while creating the receipt data will stuck in Transaction Summary form with status "Pending".

If  Processing_Mode_Code = Pending
For Workaround solution :

Change Processing_Mode_Code is Pending to Batch.

update apps.rcv_transactions_interface set PROCESSING_MODE_CODE ='BATCH' where po_header_id =1432199;

After Updation,  we can run Receiving Transaction process from Purchasing  Responsibility. Now,It will reflect in receipts.

If  Processing_Mode_Code = Error
then 
Go to Transaction Summary Form then delete error records after that re create receipts.
