Use this method to delete a job section definition field.
Important
The Jobs app is obsolete (end of life as of DataMiner 10.5.x). Starting from DataMiner 10.5.0 [CU20]/10.5.0 [CU8]/10.6.11, any related methods are no longer available.
Returns “true” if the job section definition field has been fully deleted, or “false” if the job section definition field has been hidden instead, because it has already been used previously.
