Derive values in MDG for Company Codes and Sales Areas not getting saved when logged in Spanish

Hi All

We got a derive logic to populate data for Company Codes and Sales Areas after picking Company Code's code.

Data its displayed correctly and mark in orange in the Web Dynpro as expected. After submit the Change Request, if I'm logged in english, data its saved correctly in the DDBB tables, but if logged in Spanish, data get lost and no error message its displayed.

Any suggestion where the error can be?

Thanks and regards.

Nico.-
