Row Numbering Issue

[qlikviewaf]

Hello,

Guys i'm trying to create row number by dimension (SUKEY)

I'm not getting why, for the SUKEY selected i got row NUmber = 2 ! Should be 1 since is the unique row for that SUKEY.

The script that is generation SuJoinNbr is AutoNumber(RowNo() , SUKey) as SUJoinNbr

Any idea? i'm driving crazy.

Below the full script,

THank you

BolleArchiveDraft:
LOAD

SDITM AS SUItem,
SDDOCO as SUDoc,
SDLOTN AS SULot,
SDSHAN AS SULocation,
Date(If(Len(Trim(SDADDJ))>4,Date(MakeDate(1900+Floor(SDADDJ/1000))-1+Mod(SDADDJ,1000))), 'DD/MM/YYYY') as SUShipDate,
SDSOQS/1000 AS SUQtyDraft,
SDSHAN&SDITM&SDLOTN as SUKey,
SDDELN as SUDeliveryNumber

;

SQL SELECT sddoco,SDITM,SDLOTN,SDSHAN,SDSOQS,SDADDJ,SDDELN FROM PRODDTA.F42119 WHERE SDLTTR NOT IN ('980','530') AND SDADDJ>120000 AND SDMCU IN (' EIT20',' EIT21',' EIT25') AND SDDCTO IN ('SU') AND SDDELN<>0
AND SDSOQS>0
and sdshan=233870

ORDER BY SDADDJ,SDSHAN,SDITM,SDLOTN DESC ;
