What's the difference between I-797A and I-797B

When I transferred to the new company, I got the approval notice I-797A. But there was a error of my bith date. So company filed amended H-1B. When I received the approval notice, I found it's I-797B.

Is there any difference between I-797A and I-797B?

Thank you.
