Field name must be Unique within table error

Hi,

I can't seem to load my script as I keep seeing "field name must be unique within table" as an error message which pops up and halts my run. I don't see any duplicates in my script. I have provided it below.

Please advise.

Thank you so much! ☺

v_MedicalClaim.SERVICE_DATE is listed twice in the script. Try renaming one of them and see if the you are still getting the error message.

Thank you for your response! I triple checked it again and looks like PRODUCT_TYPE was repeated twice--once at the top and at the bottom.

Thanks again :))
