When deploying a patch containing a custom data type (CDT) with an updated description, the target Appian environment still reflects the previous description after deploying the patch.
For example, if one were to update the description of a CDT from "02/02/2018: Created data type" to "02/02/2018: Created data type; 02/02/2019: Data type still maps correctly to database" in a development environment, the testing environment where the patch is deployed would still reflect only "02/02/2018: Created data type" as the CDT's description.
This occurs when the change in the object's description is the only change to the CDT. This issue has been addressed via AN-93123 in the following hotfixes/versions:
Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.
Manually modify the description in the target environment.
This article applies to all versions of Appian.
