Configuring the Operation Property
If you configure this step to update or insert a field that contains a dependency, then you must make sure the field is valid. For example, if a service request process and a Workflow Process update the area and sub area fields, then you must make sure the values chosen for the subarea field are valid for this area.
If your configuration uses a DB2 for z/OS database, and if you must use a Siebel operation step to query this database, then it is recommended that you set the Operation property to QueryBiDirectional and not to Query. Using QueryBiDirectional avoids leaving an open thread on DB2 for z/OS.
