Hi,
Please i have a question about mapping
i have field called Activity
which has the values of 1,2,3,4
i want to represent them with names A,B,C,D
so i made mapping
LOAD * Inline
[
Activity , Name
1,A
2,B
3,C
4,D
];
when i select Name it reflects to the Activity
but when i used the Activity in the expression it doesn't reflect anything
hope the attached example clarify the problem
Also I am just guessing:
=Sum({$<Activity={'$(=concat(ActivityNew,chr(39)&','&chr(39)))'}>}Value)
allows to assign multiple ActivityNew values to be assigned to Activity.
Hi Mona,
I've fixed this up for you and offered an alternative using ApplyMap() - just comment out the top part of the script and uncomment the second part.
Hope this helps,
Jason
Mona_qlik,
if you want to keep the tables not linked, you could just remove the second load from the script and change your expression in the table to
=sum(if(Activity=NewActivity,Value))
Table1:
LOAD * Inline
[
Activity,Value
1,200
1,400
1,300
2,50
2,300
3,340
3,690
4,300
4,90
];
//LOAD Activity as ActivityNew
//Resident Table1;
LOAD * Inline
[
ActivityNew,Name
1,A
2,B
3,C
4,D
];
Regards,
Stefan
P.S. Or use a mapping load with your second table and applymap in your first (you need to change the order of your tables though)
P.P.S: I would prefer Jasons second solution (essentially what I meant with my first P.S., just saw his after comitting my post)

thanks Jason for your help
but in my case as i attached iun the document i have to create another field resident the first one but this not working in the expression
i.e the field that's not reflected is the ActivityNew not the Activity
Hope the problem now is clear
Sorry Mona but I don't really understand what you're trying to achieve. Are you saying you want 2 fields with exactly the same values in them, one called Activity and one called ActivityNew?
I also don't really get what you want Mona.
If you need to keep your data model (maybe because we dont't understand your whole picture), you could use
=Sum({$<Activity={'$(=only(ActivityNew))'}>}Value)
in your table to get your / some / any results (because I ... see above).
Regards,
Stefan
Sorry Stefan and Jason
i know that my problem is complicated so above i attached a simplified example but not the real case so you can't understand what i want to do
Actually the last expression Stefan has posted is working in the case that (A) For example is reflected to (1)
which is
=Sum({$<Activity={'$(=only(ActivityNew))'}>}Value)
but what if the mapping for Name (A) is related with 2 activities (1 and 2 for example)
and i want the above expression to work with them??
If I understand you correctly (and I'm afraid I'm still not sure I do!) then both my solutions would still work in this case. Just add the second mapping to the Map table:
Activity_Map:
LOAD * Inline
[
Activity,Name
1,A
2,B
3,C
4,D
5,A
6,A
7,A
];

Also I am just guessing:
=Sum({$<Activity={'$(=concat(ActivityNew,chr(39)&','&chr(39)))'}>}Value)
allows to assign multiple ActivityNew values to be assigned to Activity.
yes Jason i did it
but now i want an equal expression to the one Stefan posted
=Sum({$<Activity={'$(=only(ActivityNew))'}>}Value)
to be used in the case of 2 Activities has the same name
is that clear?
