Context-specific documentation is not available in express mode
Valid from Pega Version 7.1.9
Help topics that are opened from express mode display content that is specific to Designer Studio.
If your system is dedicated to applications that are developed in express mode exclusively, and you do not need Designer Studio help topics, you can set the Online Help URL field on the System Settings landing page to: https://pdn.pega.com/sites/default/files/help_p7e/procomhelpmain.htm. Alternatively, you can view the contextual help system for Pega 7 Express in a separate browser tab.
Design-time limitations in express mode
Valid from Pega Version 7.1.9
Some limitations apply when you develop an enterprise application in express mode. At design time, some features are disabled or have limited options when you configure them in Designer Studio and switch to express mode. The use of these features does not restrict the run-time behavior of your application; however, you cannot change the configuration of these features unless you switch from express mode to Designer Studio.
For more information about each limitation and the recommended action to take, see the following information:
- Pega 7.2.2 Design-time limitations in express mode
- Pega 7.2.1 Design-time limitations in express mode
- Pega 7.2 Design-time limitations in express mode

Problem with truncating Decision Data Store data set
Valid from Pega Version 7.1.9
The operation for the Decision Data Store data set may cause timeout exceptions. This problem is caused by the Apache Cassandra database that waits until compaction tasks finish before it can truncate the data set.
Recommendation:
Repeat the operation until it is successful.
