KB-1902 Custom data type descriptions do not update upon patch deployment


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 reported to the Appian Product Team. The reference number for this issue is AN-93123.


Manually modify the description in the target environment.
