Synthetic error

[#1]

Hi,

          i am working with qliksense regarding folder connector. I am loading 6 different excel file into and visualize it into to one app. Upon loading it is causing me some errors like this

"

$Syn 1 = bankcode+ref_date+acct_code+peso_acct+reg_us+update_dt

---"

     What could be the possible solution for this? or other easy way for this?
