Is it possible to hide a Column on a table/pivot based on a (filter based) parameter value?
Hi,
If you are working in DV, not really… It is a right-click property only so far. There doesn't seem to be a way to dynamically influence that, or set a parameter or a condition on it.
It's maybe worth looking in https://community.oracle.com/products/oracleanalytics/categories/idealab-oracle-analytics-cloud-server if there is already an idea to make this feature "smarter" and up-vote it. If there isn't one, sounds like a good idea to create one.
You could create a case when formula to check for variable value and show blank ' ' or the actual column but this will show a blank column, its not same as hiding.
Other comments welcome!
Thanks - yes, the user does not want a blank column. They want the column gone.
Have you tried using parameters to simply create column selectors. Not exactly what you need but could help, see this video https://youtu.be/QqSrXvFhOmE
Also, here is a more convoluted path to do something similar, not the same but may help for similar cases : - if you can define your DV datasource with a SQL (a DB or a logical SQL) - then have some of the SQL query columns defined via Session Variables (OA Server Session vars) - in the canvas, define parameters to set values to these session variables (see this video https://youtu.be/LSLgmMzYp-E)
That way, the end user can further influence the definition of the datasource directly from the canvas. Again, this will not answer your need because changing the definition of the underlying source will likely simply 'break' the viz.
Added an idea here:
Thanks, up-voted !
Sorry to intervene - is this discussion is relevant to hiding the intended column from analysis in DV, based on the user login and / or based on duty application roles please ? can someone put some light on it ?
Hi @Nilanjan Biswas ,
Welcome to the Oracle Analytics community and forum.
Right now not really, because the show/hide is a manual action on the column.
If you are using a subject area, you can define security on the column in the semantic model, and that should then apply in DV as well. The column will not be visible based on the user/application role.
In "classic" it does work fine, in DV I didn't try myself, therefore can't confirm it behave like "classic", but security being enforced the user definitely will not have access to that column.
