Solution for PKS error 457: This Key is already an element of this collection
The "this key is already associated with an element of this collection" message means that there is a variable name clash somewhere. Usually this occurs when a variable is mapped as two different types (e.g. as subject identifier and also as a DCP). Any SID, Subject Data, or observation variable which is also mapped as a Time or DCP variable (Period, Phase, Treatment, and DCP) can cause this.
If the problem persists, please send the dataset and mapping files used to create the study. We will then recreate the issue on our end to determine what may be causing the variable conflict.
