Kirupasankar-

Take a look at this knowledgebase artice:

http://digital.ni.com/public.nsf/websearch/160DDB88169245B786256D600066DFB0?OpenDocument

It mentions that a finite generation requires both counters. If you want two pulse generations, you are going to have to make them continuous.

Hi Kirupasankar,

Both of the counters in the VI must be configured for continuous generation or the error will be returned, as the KnowledgeBase article describes.  Refer to the shipping example Gen Dig Pulse Train-Continuous.vi for getting started with this.  Here is a screenshot of the block diagram for such an application:
