An IBM WebSphere Commerce promotion data model has been extended and a new custom table X_PX_EXTENDEDPROMOTION is created with the key as PX_PROMOTION_ID. This new table will store Season and Year information about each promotion. An application developer has executed the Data Server Layer (DSL) Wizard and customized Management Center UI. The extended promotion information is visible in the Management Center for business users. Now, the business users would like to modify this extended promotion information through the Management Center. Considering that the information is already visible in the Management Center for business users, which two components in the DSL need to be introduced or modified to allow business users to update the custom promotion data?
