What is your pega platform/marketing version? Is this happening sporadically or consistently?

Hi,


This is in Pega Marketing 7.13 version and this is happening continuously. Please let me know, if more details require on the same.


Thanks!

Hi,


Does this exception happen for every campaign run or this particular item PR-2938 is continuously throwing the same exception ? are other campaign running in this system fine ?


Can you open the data flow work object item - PR-2938 (instance of Pega-DM-DDF-Work) in the designer portal and see what sort of errors are reported there ? there would also be a component level error reported and that would be useful to click on the link and get the status message of the failure.


Are there any campaign custom extension activities being called by taking over any Pega Marketing rules ?

Hi,


This error was for every reschedule(i.e. multiple PR runs). After trying few times, gradually records processed, and after that no error reported. But, while we pick a new set of data, this happened again.


Regards,

Hi All,


Just to confirm on this issue, I didn't find the exact root cause for this issue, but while we run campaign same as live configuration this works. So, we requested testing team to proceed with some more test based on Live configuration and see.


Thanks for your response!


Regards,


Gopesh
