Specifying extended information
You can specify additional information in the operation description. You can also use the strings to filter queries of operations.
Specify Y to have the Extended Name field appear for the operation in the current plan after you generate the daily plan or perform a dynamic addition.
Specify Y to have the Scheduling Environment Name field appear for the operation in the current plan after you generate the daily plan or perform a dynamic addition.
After it is added to the plan, the Scheduling Environment name is used at job submission time to check if the job can be submitted and if so, to appropriately tailor the JCL (by adding the JOB keyword SCHENV=SE name).
For more information, see Job scheduling and WLM.
