Pls be more specific in your question. If you want to include an extra field in your alv output, then read the field catalog table you created through "Reuse_alv_fieldcatalog_merge" and then add an extra entry in it giving the details of the field you want to add.. and then call the "resuse_alv_grid_display",
Hope this helps. To be able to help you in a better way, kindly revert with any specific issue.
