Syntax error, unexpected symbol at or near 'groupped'

Question

I've the following code:

Input_File = load '/user/cloudera/teste' USING PigStorage (' ')
      as (ID:Int, 
          Descrip:Chararray,
          Date:Datetime);

groupped = group Input_File by (ID, Date);

ranked = foreach groupped {
        ranked = rank groupped by ID desc DENSE;
        generate flatten(ranked);
        }

STORE ranked into '/user/cloudera/teste1123';

I'm trying to create rank column on this dataset:

id  des date
1   A   01-01-2016
2   A   02-01-2016
2   C   03-01-2016
2   D   03-01-2016
3   A   01-01-2016

The main goal is to get this:

rank    id  desc    date
1       1   A   01-01-2016
2       2   A   02-01-2016
3       2   C   03-01-2016
3       2   D   03-01-2016
4       3   A   01-01-2016

But when I'm running my code I'm getting the following error:

ERROR 1200: <line 5, column 14>  Syntax error, unexpected symbol at or near 'groupped'

What I am doing wrong?

Many thanks!

Not sure where the syntax error is, however here is the solution you are looking for.

Note: You will have to load date as chararray

Input_File = load '/user/cloudera/teste' USING PigStorage(' ') as (ID:int, Descrip:chararray,Date:chararray);
ranked = rank Input_File by ID ASC,Date DENSE;
dump ranked;

Output
