can anyone tell me how to do these actions
You don't have to write the logic for deleting the record from R/3 in your WD application.
Ask ABAP guy to create a BAPI for your which takes in the purchase order number as an input and delete the record from R/3 for the corresponding purchase order number.
The method for executing that BAPI would be same as you have mentioned. You just need to execute the BAPI. All the logic to delete the record in the R/3 would be handled in BAPI itself.
Hope, I am clear now.
