DSOs not visible in selection field - SAP BI security

Hi Experts,

This is a BI 7.4 security question .While trying to  provide authorization for certain DSO , I found that it is not available in selection field. Could you please guide me. In the below mentioned picture, I am suppose to see standard DSO's PQ080ER1 , PQ080CA1 and PQ080UC1, when I press F4. But nothing pops up.  Authorization object used is S_RS_ODSO and field name is  RSODSOBJ.

Thanks and Regards,

Syam
