by "perform all operations" what does this refer to? I can;t find any way in Qlikview of entering data or creating calculations as a user, so I understood this needed the Kliqplan bolt on, but this has apparently only just been released and is presumably unproven.
Are you able to enter data and run budgets as a user (ie not an administrator?)
QV provides the INPUTFIELD feature which allows for "what if" analysis. It has some limitations, but can be successful in implementing scenarios like planning and forecasting.
INPUTFIELD values are remembered between sessions for a user. There is no native writeback capability, so you cannot have a user update a shared master plan without writing some code.
I don't want to extol the virtues of our solution. Here you can find the opinion of Olof Malmström from Climber (one of our leading partners): http://community.qlik.com/message/267446.
We only sell our solutions through partners.
If you are an end user you can get all the info from Climber. If you are a QlikView partner please contact us (https://ktlabs.wufoo.eu/forms/information-request-form/) and we will be glad to give you a full overview with a live demo.
