Building a cube fails with the following error:
(TR0120) Transformer can't write to a file. [->OK]
Resolving The Problem
In this specific scenario the resolution was to point all directories in IBM Cognos BI Transformer - File - Preferences - Directories tab to point to a drive with a larger amount of free disk space. Also setting the Auto-Partition slide to the middle rather then to the right (Faster Cube Access) using the following steps:
1. Open the Transformer Model
2. Right-Click the Cube
4. Auto-Partition tab
5. Slide the Partitioning to the middle
6. Click 'OK' to close and save the model.
7. Build the cube.
Note: This was symptom that was resolved with the above specific steps.
