How to remove data type changes

[DSmith4]

Hi,

I have a datasource connected to SAP business warehouse. I tried refreshing it and recieved the OLE DB or ODBC error DISP_E_TYPEMISMATCH error. based on what I can see online it appears this is because I changed the data type to something that cannot be handled by the application. 

I tried to change this back however I am unable to delete the step. When I set the data types, I did from the modelling tab. Any way to correct this? Im not sure what the original data types were before I changed them. 

Thanks,

I set all data type to text and was able to refresh

If you have changed data type in Edit Query mode then you will get step. If you have done it in the Data view then you will not get the step. Just change it again to original
