Sunil,
V7 of AC automatically sends a summary of that day's appointment when the note is signed as well. This meets MU2 core 8. However, to meet criteria for MU2 core 7 in AC you have to send a "Full Patient Record" clinical summary, and there is no way to automatically do this.
And also, it sends it as a CCD-A, overwriting in the portal, the encounter summary sent when the note is signed.
