Hello Anders, 

Thanks for your response and informing about the fact since I am very new and I have no idea what to do ! 

Well how am i am going to release my current PDI and request a fresh installation? but myself through any setting or need to contact support ?

I believe I have to do since no way I am able to create the scope app , even changing the names each time with complete new names but same error. 

Appreciate your response Anders and thanks again for your comment on my post. 

Regards
Subrata
