Long running of DTP with processing mode 'No data transfer, delta status in source'

In Info Package we have option called "Init witout data transfer" to set the delta status in source without picking data. In the same way, in DTP we have option called "No data transfer, delta status in source" which serves the same purpose. You can find this option in Excute tab, processing mode.

This job will run as dailoge, you can not run this as background. Sometimes if you have lot of requests in source, then this will take lot of time.

If you face any issue in this process, you can refer the below Sap notes.
