Compilation Checks

During compilation, the following criteria in the job design are checked:

• Primary Input. If you have more than one input link to a Transformer stage, the compiler checks that one is defined as the primary input link.
• Reference Input. If you have reference inputs defined in a Transformer stage, the compiler checks that these are not from sequential files.
• Key Expressions. If you have key fields specified in your column definitions, the compiler checks that there are key expressions joining the data tables.
• Transforms. If you have specified a transform, the compiler checks that this is a suitable transform for the data type.
