I experienced that there is a system limit within the SalesForce.com suite: there is NO possibility to set up the campaigns hierarchy in case the single campaigns have been created with a different currency from the parent one.
This is vital for our organization and for all the multinational companies which would like to identify the overall costs of a strategic campaigns declined in the different territories and also to calculate the ROI.
The system itself has been projected to have in all the Object with a field currency the correspondent field ‘converted’ in order to have all the amounts also in the consolidated currency: the user could easily use on setting up a hierarchical campaigns report the currency ‘converted’ fields to summarize.
I hope that the SalesForce developing team should recover immediately: please click on the IDEA link below to vote.
Thank you for your help.
