How to avoid Carriage return in external Data source fields

Dear BW Experts,

We have an external data source and loading it from a .CSV file.

Some of the fields like address field and description field have carriage return in the field.

This causes error while loading the datasource from the .CSV file. The external system is unable to correct the same.

Could you advise as to how to fix the issue.

Thanks,

Sai
