Filter only biggest autonumber

[MT4T]

Hello, 

I have this table and I need filter only the rows with the biggest value in field "appear". Which was generated with autonumber function. How to do this ? 

FIS3:

CROSSTABLE (Atribute,Value,28)

//NoConcatenate
Load
AutoNumber(Recno(), REF) as appear,
*

RESIDENT FIS

@MT4T  try below

FIS3:
CROSSTABLE (Atribute,Value,28)
//NoConcatenate
Load
AutoNumber(Recno(), REF) as appear,
*
RESIDENT FIS;

max:
LOAD max(num(fieldvalue('appear',recno()))) as max_appear
autogenerate fieldvaluecount('appear');

let vMax_Appear =peek('max_appear',0,'max');

drop table max ;

FIS4:
noconcatenate
LOAD *
RESIDENT FIS3
WHERE appear = '$(vMax_Appear)';

DROP TABLE FIS3;

Sorry, I need to load only max "appear" within subgroup "REF". Your solution load only one max "appear" top of all.

I believe there should be some sibling column to "appear" which shows max recno() per subgroup. And filter should look like this:

Where "appear" = "max_appear"

but i do not know how to do max(recno()) thing.

Do you need to consider any additional dimensions? Like the biggest "appear" for every customer?

try below

FIS3:
CROSSTABLE (Atribute,Value,28)
//NoConcatenate
Load
AutoNumber(Recno(), REF) as appear,
*
RESIDENT FIS;

Inner join (FIS3)
LOAD REF,
max(appear)as appear
resident FIS3
group by REF;

Thank you! I never thought that inner join could be used as a filter.
