Error when converting Part Number to Text

Hello

Recently I'm trying to create a report where I have to add the part numbers we have in our system. Some part numbers have letter and other extra numbers like

7225100.0.02

or

7225100.P

When I import the Excel file to PBI that error appear:

I tried to convert to "Text", and "Any" but this error still persist. Do some one have any idea? 

Thanks
