Process Analytics logs continuously generated in Appian 17.2

Incremental update errors indicate a problem propagating data to the analytics engines. If you're encountering those errors, you'll likely encounter problems with process reports and related functionality. 

The best thing to do would be to create a support case. I'd also encourage you to update Appian to a more recent version, as there have been significant improvements made to the incremental update functionality since 17.2 . 

thanks for your answer. doing the upgrade again solved this Problem. We are planning to upgrade to 18.4 but we cant do it directly
