Providing you have the required security access, it is possible to review process errors from within the TM1 Server Explorer.
Right click on your model name (CXMD is the default) and then select 'View Message Log...'
You will then see a list of server messages (be aware that usually this is shown in UTC time)
This log file is also accessible from the logging directory on the server where the TM1 model is located.
If you have just had a process error then this would no located at the top of the Message Log.
The most common kind of TM1 TI (Turbo Integrator) process errors we get is where a new elements either does not exist, or has not had it's mappings applied.
You will see a message on the log file indicating that 'Element "*" not found.
Often this can occur when changes have been applied to the data source, and the user is attempting to to do a data load. If the changes in the data source have included new elements (e.g. Accounts or Cost Centers) then it may be necessary to also run the dimension build processes for these dimensions so that the new elements are created before data can be loaded against them.
This error can also occur when the process attempts to lookup another element that has yet been defined. It may be that the required attributes have not been defined. We normally provide administration options under 'Applications' for this purpose.
Another common type of process error can occur when TM1 could not connect to the data source. Perhaps there was a network connection or server issue during the night.
The overnight processes can be run during the day to ensure that data is updated, however please be aware that this may cause poor performance and some cubes not being available for other users during this time.
There are many other possible causes of TI process issues. If the process has worked in the past, then this would indicate that there was a change to the data the is not being handled appropriately.
Our support team are available to review error logs and trace the cause of errors providing analysis of the cause and to propose a solution.
