Content (please ensure you mask any confidential information):

We have one LE, for which we wish to create multiple Legal Reporting Unit's. We intent to associate each LRU to a distinct Regime, Tax and Jurisdiction, which will have distinct tax currency and a country. Is this possible?
1. Can we report a single transaction via all these different LRU's?
2. When we create a transaction (E.g.: Payables invoice) how would the system know to which LRU it should associate the transaction?
3. Finally how can we use the LRU for our reporting? Do we have to develop custom reports that would have a dropdown of all the LRU values?
