SSIS Import Excel File with Dynamic Columns

Good day,

I have been battling to import an excel file where i have an itemcode in columnA and from columnB Customers per column

my dft keeps failing as every month we receive the file from external vendor whee customer columns moved and additional.

please is there anyway to import with failing, therefater i apply a unpivot

Example: Import        > ItemCode, Cust1,Cust9,Cust7,Cust2....

              SSIS Unpivot> ItemCode,Customer,Qty

But my import fails everytime and i can build the exception but i have to manually change the package

Please help
