Hi Sean;

What I have to do is so simple; just to read the last record added to
each group.

Field PROC represent the group ID.

Field MOVI represent a unique primary key for each record in MOVI.

Field FECH represent the date/time of the imput as a string litereal in
format YYYYMMDDHHMM (YEAR-MONTH-DAY-OUR-MINUTES).

I have to read the last full record of each group. The table is so big,
may be 50.000 or more groups and 30 or more records each group.
