calling SAP transactional iview with multiple values from WDA application

Hi all,

1. I use the transaction iView to call SAP transaction from my WDA application using method 'Navigate_absolute'.

    I already pass parameter like "sales order Number" with the parameter "S_VBELN-LOW" and it works fine.

   Now I would like to pass multiple values(not range) of this type - e.g. the numbers 001,005,012,101like these numbers i need

   to pass to the selection screen of calling SAP transaction.

2. Also please tell me how to execute selection screen automatically ( i.e when i call SAP transaction iview from WDA application 

   the corresponding transaction needs to execute and display the results based on the values that i passed to the application)

can anybody please helpme on this.

Thanks,

Naveen
