The initial release of IBM Cognos Transformer 8 contained no programmatic automation support. You had to script using MDL, the Transformer Model Definition language. Now, IBM Cognos Transformer re-instates OLE automation with updated Active X controls to allow .Net support and new C8.3 functionality for the 8.4 release and also adds support for new IBM Cognos Transformer 8 features and functionality, including security.
If you are an IBM Cognos Series 7 customer who is currently using IBM Cognos PowerPlay Transformer OLE automation, you will need to upgrade your code to leverage the new IBM Cognos 8 OLE functionality.
