I'm not sure I follow you, are you creating the Group in live data source and then switching to Extract? You'll have to create the extract again when you make changes. Or, you can just create the grouping in Extract itself.

To follow on from Shivaram's question, what do you mean by "replaced"?

Are you refreshing the data in the extract, or are you doing a "Replace data source" activity?  If you're doing the latter, that's likely the cause of the issue.

Hi Conacher,

Instead of replacing data source, have you tried to refresh extracts ?

Another alternative would be to create a calculated field off the native fields, then when you replace the data this isn't affected because instead of aliases your viz will be looking for a calculated field to do all the work.

Like Peter suggested, instead of creating groups explicitly, try using a calculated field to create the groups, so the calc field recognizes new data and groups them as it should. It would look something like this,

IF [AGE] <= 29 THEN "29 and Under"

ELSEIF [AGE] >= 30 AND [AGE] <= 39 THEN "30-39"

ELSEIF [AGE] >= 40 AND [AGE] <= 49 THEN "40-49"

.

.

.

.

END

You'd have to replace the groups with newly created calc field in the views.

Hope this helps.

Best,

Shiva

Hello Conacher,

I think Calculation would solve the problem.

Have you tried @peter fakan solution; calculated field?

Hope it helps.
