Order is stuck in the MO status (Manual operation required) with the comment "There are Serice Parameters to be filled manually". Some service template parameters marked as system and non-editable were changed: parameter "Is Required" set to No and it is not possible to change the value back.
The root cause of the issue is a bug with id #PBA-66801 ("During System service parameters update in service template wrong values are saved"). Some of the service parameters were wrongly set as not required and not asked on order placement. Please contact Odin Technical Support Team to set the correct values for the parameters. To avoid values to be reset again update BA to 6.0.7 or above.
To provision the current order go to Home > Operations > Orders > Order ID > Provisioning Items, choose item and fill in the parameter(s).
