Loading data from another module: Data is ignored when loading to Version
I have one module called DAT01, which contains employee census data. There are two others modules called DAT02a and DAT02b, which are identical with the exception that DAT02b applies to all versions whereas DAT02a does not apply to any versions. DAT01 only has one dimension, which is a unique ID containing a combination of period, department, and employee ID. DAT02a and DAT02b have the dimensions time, department, and employee.
I have an action that loads data from DAT01 to DAT02a and loads the dimension values prior to loading the data to the module. E.g., the data is transformed so that the relevant dimensions appropriately apply to the data. The problem I'm running into is when I try to run an identical action to load data to DAT02b. For some reason when I run this action, every single data item is ignored (see screenshot). The only difference is that DAT02b has Version as a dimension and the action requires that you select the Version for loading when the action is run.
Any ideas? Am I missing something fundamental about Anaplan here?
