How can we remove order type from the pophelp without deleting the same from order type masters ?

Suggestions:
System has the provision to make the order type as inactive in the order type master. In distribution order type, the field is ‘Available’ Y/N.
Menu Path: SCM – Masters – Distribution Order type. This master is used to set the initial values for some fields in the Distribution Order. The values can be set as editable or non-editable fields. Available (Y/N) should be selected from the drop down values. It indicates whether the order type is active/ inactive.
