Presentation Variable in obiee 11g

Question

Hi all ,
I had a dashboard report with year , quarter , month and order type name as prompts .
Now my client requirement is , when order type name is "Ord" , the reports with order type name starting with 'ORD" should be displayed.
In simple i know we will use " Like" operator .
But now my problem is we have to assign a presentation variable for order type name.
So can some one tell me how to add a presentation variable in OBIEE 11g , i tried in web , but none of it helped me to finish the job ,, since i am very new to obiee can some one please explain me in non technical language
Thank you for your help

Hi Jay , Thank you very much for reply , now i got a little idea , but few doubts abt ur reply .
Yes i will edit dashboard prompt and assign a like operator and will save the prompt , but when editing the report , you said to apply a filter *LIKE @{presentation_variable}{default_value}%*
In the above what will be in place of presentation_variable and what should be in default_value.
I have tried it in this way : Like @{Sales Order Lines Order Type Name} , where Sales Order Lines Order Type Name is my dashboard prompt .
but it didn't worked when i have given 'Ord' in dashboard prompt the error says: Sales Order Lines Order Type Name is LIKE (pattern match) ord
