APP-FND-00806: The default value ES is invalid for the B2G Electronic Invoice Languag segment

Hi All,

Need your help to know if the following message is an error, a missing setup or a low patch level:

APP-FND-00806: The default value ES is invalid for the B2G Electronic Invoice Languag segment. Your default value will be ignored. Please inform your system administrator that:

Add the value ES to the value set for segment B2G Electronic Invoice Languag, or choose another default value in the Key Flexfield Segments form or Descriptive Flexfield Segments form. Use the Edit Concurrent Program or Define Report Set form for Standard Report Submission report defaults.

I get the error message when entering information in the Transactions Workbench window in AR.
