Creating Flag in script to achieve desired outcome with multiple conditions

[s10157754]

Dear Qlikview Experts,

I wanted to create a Flag in the script to get my desired output in the table. The condition for Flag to display as 1 would be:

1) If Step1 and Step2 and Step3 and Step4 all are blank cells

    Or

2) If anyone of the 4 fields (Step1 / Step2 / Step3 / Step4 ) Contains ONLY 52 but not other values.

The script that I am using currently is:

t1:
Load *,
If((Len(Trim(Step1)) = 0 and Len(Trim(Step2)) = 0 and Len(Trim(Step3)) = 0 and Len(Trim(Step4)) = 0) or
((Step1 = 52 and RangeSum(Step2,Step3,Step4) = 0) or
(Step2 = 52 and RangeSum(Step1,Step2,Step3) = 0) or
(Step3 = 52 and RangeSum(Step1,Step2,Step4) = 0) or
(Step4 = 52 and RangeSum(Step1,Step2,Step3) = 0)), 1, 0) as Flag;
LOAD
@1 as Step1,
@2 as Step2,
@3 as Step3,
@4 as Step4
FROM
(txt, codepage is 1252, no labels, delimiter is ';', msq);

I had tried to change my logic conditions in the script but still unable to get the correct output. I had attached a sample of qvw and txt log file to ease your reference. Appreciate your time to help me solve this problem! Thank you for your time in advance!

Best Regards

The problem that you use the function Rangesum with values that are not numbers and this is why is returned an incorrect value. Try the following code:

t1:

Load *,

If((Len(Trim(Step1)) = 0 and Len(Trim(Step2)) = 0 and Len(Trim(Step3)) = 0 and Len(Trim(Step4)) = 0) or

(Step1 = 52 and Len(Trim(Step2)) = 0 and Len(Trim(Step3)) = 0 and Len(Trim(Step4)) = 0) or

(Step2 = 52 and Len(Trim(Step1)) = 0 and Len(Trim(Step2)) = 0 and Len(Trim(Step3)) = 0) or

(Step3 = 52 and Len(Trim(Step1)) = 0 and Len(Trim(Step2)) = 0 and Len(Trim(Step4)) = 0) or

(Step4 = 52 and Len(Trim(Step1)) = 0 and Len(Trim(Step2)) = 0 and Len(Trim(Step3)) = 0), 1, 0) as Flag

;

LOAD

@1 as Step1,

@2 as Step2,

@3 as Step3,

@4 as Step4

FROM

(txt, codepage is 1252, no labels, delimiter is ';', msq);
