Issue/Symptoms

When running the workflow, the following error is thrown by the Update data activity:

writer Attribut 'Fldxxxxxxx' inconnu (voir définition du schéma 'Mise à jour de données (temp:writer-work)')

Cause

The error occurs because the workflow is trying to update a field that does not exist in the target schema.

Resolution resolution

To resolve the issue, follow these steps:

  1. Identify the field mentioned in the error message.
  2. Open the workflow XML and search for the field ID referenced in the error (the number after FId).
  3. Go to the schema you are trying to update and make sure this field exists there—not only in the workflow.
  4. If the field is missing and should be present, add it to the schema.
  5. If it should not be present, remove it from the Update Data activity in the workflow.
