RQP-DEF-0055 Unable to find the query subject for the ID: 0:0. S Samman asked Jul 13, 2011 | Replies (2) Good day All, I have a report that has been running for a year , and suddenly this error message pops up , I can't find a proper description for it on the net to address it. I am using Cognos Report Studio 8.3, the report is made out of 2 running queries ( tested them separately with no problem). I have identified the field that may be causing the problem when added to the combined query, but it is strange as it is not the field used to link the 2 queries . and as i said both queries are running properly. Hope someone came across the sa
Sometimes 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 http://businessintelligence.ittoolbox.com/groups/technical-functional/cognos8-l/rqpdef0055-unable-to-find-the-query-subject-for-the-id-00-4306788 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 8 server to do query processing rather than having the database do the query processing (so basically, "Local Processing" is occurring rather than http://www-01.ibm.com/support/docview.wss?uid=swg21341798 "Database Processing." Symptom RQP-DEF-0103 Cross joins (between query subjects X and Y) are not permitted for the user who has the identity (XXXXYYYYZZZZ) Cause No Relationship between tables at the model level Resolving the problem There are a few different ways to circumvent this error: A. Find a different way to achieve the desired results that does not end up in a cross join. B. Enable cross joins for the query causing the error. C. Enable cross joins in the model. Note that enabling cross joins is not always the best solution - especially when it would involve doing a cross join between very large tables. Cross joins between large tables can take a long time to complete. In this case, it might be best to find an alternative way to achieve the end reporting goal without using cross joins. Steps: B. Enable cross joins for the query causing the error 1. Open the report in Report Studio. 2. Navigate to the Query Explorer, and then the 'Queries' folder. 3. Click the query that is experiencing the cross join error. 4. In the P
