Cannot upload feed. Columns in feed exceeds limit for this user account.

Error Message: Cannot upload feed. Columns in feed exceeds limit for this user account.

Reason for Error: This error is generated upon initial transformation only. This error means the number of the columns in the feed exceeds 100, which is the backend limitation set by Studio.

Resolution: There are a few steps you can take to resolve column limitation issues:

1. Think about revising your feed structure:
   1. You can split the creative elements into multiple feeds (tabs within the same spreadsheet) to stay under the 100 column limit per feed. 
   2. If you have a single feed that includes multiple creative sizes broken out into columns, you can split each size onto a separate feed (tab within the same spreadsheet).
2. If you are unable to revise your feed structure, contact your Rich Media Solutions Consultant.
