Nicole, you could modify the web pages for this purpose. The two web forms will be detail_chg.htmpl and order_status_change.htmpl. For example, for detail_chg.htmpl, you can modify it to"
<PDM_IF "$args.category.sym" == "AAA">
<PDM_MACRO name=dtlDropdown hdr="Status" attr=status whereclause="id<>6001">
<PDM_ELSE>
<PDM_MACRO name=dtlDropdown hdr="Status" attr=status>
</PDM_IF>"
from "
<PDM_MACRO name=dtlDropdown hdr="Status" attr=status>
"
here I assume the category you don't want users to close the change order is "AAA" and the id 6001 is the out
of box id for change order status "Closed". Similar change should be done for order_status_change.htmpl
This way, no one will be able to close the change order if its category is AAA, from the web interface. However,
thru PM, as it does not use web forms the specific service account will be able to close the change order.
Hope this helps. Thanks _Chi
