TECHSAP : 3.BAPI- Difference Between Non Dialog & Dialog BAPI with example.

Dialog BAPIs usually calls the Screen where the user is required and it can not be executed in background where as with Non Dialog BAPIs can be called in Background mode without any User intervention. The below post shows the difference between the two types.

--------------------------------------------------------------------------------------------------------------
Step1. Go to Tx- SWO1 & open the BO- BUS2032 Sales order. The two methods creates the Sales Order but one without dialog mode and other is with dialog mode.

Step2. The associated FMs with the BAPI Methods.

Step3. Create the below report which created the Sales Order By Non Dialog BAPI FM call.

Step5. Execute both the report and see the output.

Step6. The first one directly creates the Sales Order & the other Dialog BAPI calls the transaction VA01 and waits for the user action like Save or modifying something in the Screen.
