We have a requirement to add around 10 fields in the notification . We do NOT want to append the standard table and would like that these fields should reside in the Z table only. The data exchange related to any form that is Save, change or display should happen from Z table and custom table toghether. Can we acheive this via BADI or an exit so as to not append any standard SAP structure. We have a further requirement that these custom fields should be displayed in a SAP report.
