I need to add a sales area dependant field in the Shiping Terms assignment block of Business Partner. I appended a strucuture with my field to the structure CRMM_BUT_SET0020 and added the field to the configuration . The field is now appearing in the web ui shipping terms block. But when I enter any value and press enter the value is not getting held, its dissapearing. Could you please let me know the reason for this.
