I have recently created a pre-condition which performs a calculation (BOO - argh!) and placed it into a process. However I cannot edit the calculation even when I de-activate the only process that uses it. On selecting the BO all Condition parameters - except Condition - are greyed out. No parameters appear to be editable.
The pre-condition is indicated with the 'stop sign' in the icon to indicate it can't be deleted.
Is this expected behaviour, or am I missing something?
