What are the chances of approval of H1B extension after getting RFE after approval for H1B in PP

I am on H1B visa. My company applied for H1B extension in premium cap and I got approval and even physical copy of approval from my company. The very next day after getting physical copy i got mail from my company that I have got RFE and need to submit a list of documents. Has any one faced the same problem and what will happen next. If I check online it shows viisa approved on march 15 and physical document sent. Please help…

I think its a documentation error. Respond with your approved I797.
