Hi Janice--
No, you shouldn't have a problem with this. The keys are both assigned to different dimensions and thus to different parameters. IN the loader, the key values are specific to the Dimension you're loading.
If you're talking about values displayed in the Dimension, and used in a drillout to an operational report, the answer is, they're still assigned to different dimensions, so though the two Dimension Level values would be the same, they are exposed via different parameter names.
How you finally map and use them in operational reports is up to you. You could toss them together and just say, whatever the Dimension is, here's the value to use as a filter. Or you could use them a separate filters.
Hope this answers your question.
