LSATs Not Populating

Trying to use an LSAT for a fact table query, when I noticed that it was empty. I reinitialized the data from PSA to STG, which, should have popualted the LNK and LSAT.
    
Reran the RDV load again.

LSAT is still empty even though LNK is populated.

What gives? 

The issue here seems to be that you need to Accelerate your model, but first ensure that BACKBONE is set to 'off' and then click `Publish.`

You should now see the correct mappings for the LSAT when looking at Column Mappings.

Please reply if this does not resolve your issue.
