Error RQP-DEF-0103 Cross joins are not permitted when using Cognos Analytics Reporting

Troubleshooting


Problem

For Cognos Business Intelligence please use the following technote: http://www-01.ibm.com/support/docview.wss?uid=swg21341798 In certain reporting situations, a user will inadvertently create a cross join. A cross join is a join between two query subjects that do not have any links at the model level (or in some cases at the database level). This can happen under a wide variety of conditions. For example, in a model, there may be a table which is standalone because it is a lookup table that is used to create filters when filtering other query subjects. In this case, when a user attempts to include query items from the lookup table in a filter on a query subject in the model, a cross join would be created. The reason Cross Joins are not desirable is because they cause the Cognos server to do query processing rather than having the database do the query processing (so basically, "Local Processing" is occurring rather than "Database Processing."
