Previous MONTH ID should be zero

[qlikview979]

Hi All,

Please find attached Qlik app

I have data like below

ID	PRODUCT	SALES	MONTH	YEAR
1	A	100	August	2018
2	B	200	September	2018
3	C	300	October	2018
4	D	400	November	2018
5	E	500	December	2018

LOAD ID,
PRODUCT,
SALES,
MONTH,
if(Left(MONTH,3)='Aug',8,if(Left(MONTH,3)='Sep',9,if(Left(MONTH,3)='Oct',10,if(Left(MONTH,3)='Nov',11,if(Left(MONTH,3)='Dec',12))))) as MONTH_ID,
YEAR
FROM
test.xlsx]
 (ooxml, embedded labels, table is Test);

I have created two variables for

vMaxmonthid=max(MONTH_ID)

vMinmonthid=(max(MONTH_ID)-1)

and if i select August month as  its showing maxmonthid is 8 and minmonthid is showing 7.

Here i don't have July month so min variable should be show Zero in variable level.It means if i don't have previous month data in it should show zero.

How to handle this scenario in qlikview can you help me on this?

Hi,

Please try below code, it works in my sample:

set vMaxmonthid = max(MONTH_ID);
set vMinmonthid = if(max(MONTH_ID) - 1 < min({<MONTH_ID=>}MONTH_ID),0,max(MONTH_ID) - 1);

And in the front-end, you can use $() to get the variable value.

Please try.
