You remove a system template from a business rule's flow chart by right-clicking it in the flow chart, and selecting Remove. When you remove it from the flow chart, it is not deleted from the database. It exists in the database as a separate object.
To remove a system template from a flow chart:
In the System View, expand the Planning or Essbase application type, the application, the plan type (for Planning), or the database (for Essbase), and Rules.
Right-click the business rule from which you want to remove the system template, and select Open.
In the flow chart of the Rule Designer, right-click the system template you want to remove, and select Remove.
