The DP BATCH EQQDPX01 exit

Exit EQQDPX01 can be used to set or change a scheduling environment name when creating the daily plan batch, according to user specifications (you can apply your own rules to set the values). Depending on how you implement it, this exit might affect the performance of the batch creation process, because it is called for each new operation (non-FTA) in the plan. For this reason, use this exit only when really necessary and try to avoid time consuming processing, like for example, unnecessary I/O (for instance, open the file at the first call and close it at the last call).
