I have created Journey with data extension as entry source and which updates Contacts and Custom object records , using values from data extension, however i do not see contacts entering in journey after i scheduled the JB it says 0 contacts evaluated, 0 entered Journey. any Leads highly appreciated.
Check the Journey Settings and Contact Entry. If you have the settings on
No re-entry then the contacts will not enter back into the journey.
Journey Builder has what is called a "high water mark." The data extension you are using may not be detecting new rows because new data was not added to the data extensions.
The high water mark tracks the last event processed for the event source data extensions. Only records above this high water mark will be processed and records below this high water mark will be ignored.
