After a LIVE deployment, do not remove forms or items from your InForm study

• Recommendation: Do not remove forms or items after you deploy your InForm study to LIVE.

• Rationale: When you remove a form or item after a LIVE deployment, the database column that corresponds to the removed form or item is removed from the reporting schema for the study. This causes destructive changes to the InForm data model in the DMW Production lifecycle.

• Additional information: Instead of removing a form:

  • Add a global condition to the study, and include a triggering condition for the form that can't be met. As a result, the form is not triggered to appear for additional subjects.

    For example:

    this.<visitrefname>.<formrefname>.<sectionrefname>.<itemrefname>.Empty && 1==2

  • Make sure that the refpath that you use is for a valid item in the study so that the expression is properly validated and attached to the study design.

  Instead of removing an item:

  • Create an in-place study revision and configure the following properties for the item:

    • Display Override - Hidden

    • SDV Required - False

    • Required - False
