Thank you for your reply. 
Because we need to count the amount of source data and target data processed by 
each task, 
we must be able to obtain DS tasks in my own execution program_ instance_ id.

?????? ??????????????????????process_instance_id????????shell????
I don't quite understand the actual scene, can you describe it in detail. In my 
point, the business side should not care about the internal parameters of DS.
For better communication, please use English. Thx.
