“TE_7020 Unbound field in Source Qualifier” when running session

Problem Description

TE_7020 Unbound field in Source Qualifier

Informatica Error – TE_7020 Unbound field in Source Qualifier

When running a session the session fails with the following error:

“TE_7020 Unbound field in Source Qualifier”

This error will occur when there is an inconsistency between the Source Qualifier and the source table.
Either there is a field in the Source Qualifier that is not in the physical table or there is a column of the source object that has no link to the corresponding port in the Source Qualifier.

  1. To resolve this, re-import the source definition into the Source Analyzer in Designer.
  2. Bring the new Source definition into the mapping.
    This will also re-create the Source Qualifier.
  3. Connect the new Source Qualifier to the rest of the mapping as before.
