Hi,

please check below example script and output.

T1:
LOAD
AutoNumber(Rowno())as RowLine

FROM
[C:\Users\Desktop\QlikView Straight table files.xlsx]
(ooxml, embedded labels, table is Sheet1);

T2:
Load RowLine,if( RowLine-2<=0,-1,(RowLine-2)) as Result Resident T1;

b:
load a,b, a-b as diff,
rowno() as row,
if (peek(diff)>0, if(diff<0,1,0),0) as Flag
Resident a;

NoConcatenate
c:
load *
Resident b
where Flag =1;

 

let vnum= Peek('diff',0,c);


ans:
load diff,
if(diff= $(vnum), -1 , diff) as actual_diff
resident b;
drop table c,b;

This way you will get 1 as flag for 1st occurence of negative difference.
