The issue i have is, i don't have a field modifier to work with,
From a data table, i filter the data in a bookmark to have the top 10 based on ranking, these ranks can be identical(tied ranks) so i cannot search rank as a field modifier.
Is there a way to target a specific row of data without know any of the field modifiers?
something in the line of, get rank from row number 3, etc ?
Sorry for the late update, but i think you got the gist of what i'm trying to do.
And your suggestion is workable if i do create a unique identifier, but Im trying to avoid this calculation set due to large volume of data.
But to further elaborate, my original question is whether there is a way to target a specific row of data by only knowing the row number,
For example, with the following table :
Item
Rank
Value
Text
21
1
99
AA
2
2
80
BB
15
2
80
CC
4
3
77
DD
8
4
60
EE
Is there a way to get the text "CC" in a text box object by only knowing it will be the 3rd record row ?
Item number is my unique identifier, but the number is unknown as data will varies, since when filter by top ranks, the rest is omitted. I need to get the text column, but only available information is that the 1st row will be my 1st rank, 2nd row, 2nd rank, etc..
Evaluates expression, compares the result with the result of the other rows containing the current column segment
and returns the ranking of the current row within the segment. For bitmap charts, the current column
segment is defined as it appears in the chart's straight table equivalent (Actually all QlikView charts have a
straight table equivalent with the exception of the pivot table which has a more complex structure).
If the chart is one-dimensional or if the expression is preceded by the total qualifier, the current column segment
is always equal to the entire column. If the table or table equivalent has multiple vertical dimensions,
the current column segment will include only rows with the same values as the current row in all dimension
columns except for the column showing the last dimension in the inter field sort order.
The ranking is returned as a dual value, which in the case when each row has a unique ranking will be an
integer between 1 and the number of rows in the current column segment.
In the case where several rows share the same ranking, the text and number representation can be controlled
as follows:
The second parameter mode specifies the number representation of the function result.
mode
0 (default) If all ranks within the sharing group fall on the low side of the middle value of the entire ranking, all rows get the lowest rank within the sharing group.If all ranks within the sharing group fall on the high side of the middle value of the entire ranking, all rows get the highest rank within the sharing group.If ranks within the sharing group span over the middle value of the entire ranking, all rows get the value corresponding to the average of the top and bottom ranking in the entire column segment.
1 Lowest rank on all rows.
2 Average rank on all rows.
3 Highest rank on all rows.
4 Lowest rank on first row, then incremented by one for each row.
The third parameter format specifies the text representation of the function result.
format
0 (default) Low value&' - '&high value on all rows (e.g. 3 - 4).
1 Low value on all rows.
2 Low value on first row, blank on the following rows.
The order of rows for mode 4 and format 2 is determined by the sort order of the chart dimensions.
Examples:
rank( sum( Sales ))
rank( sum( Sales ), 2 )
rank( sum( Sales ), 0, 1 )

parameter 4 is used to determine how to handle ties (i.e. assign rank 2 & 3 in your example).
sum(Value) is just the expression that determines the rank (it is evaluated per item in the field modifier search expression). In your example, one could also just use rank( Value ,4), because there is only one value per item in the sample data.
Of course you don't need the slider, just use the set expression.
