Returning rowcount using SysTableRowCount Form in Dynamics AX

Accidentally bumped onto this form called SysTableRowCount in Dynamics AX, It's pretty handy to get the recordcount remaining in AX. And, it's there in all the 3 versions of AX: 4.0, 2009 and 2012. Good to know something new.

Alternatively, if you have SSMS (SQL Server Management Studio), you can always fire, select count(*) from <tablename>
