Hap_document cant export the result as in PP_MY_APP MY_APPRAISALS

Hello all,

when we see the appraisal document in complete stage through PP_MY_APP ,we get options to export.

however when i do same through HAP_DOCUMENT(page: document_recieved) i get a similar screen with all the data but there is no option to export the result .

Do we have to do some modification in BSP HAP_DOCUMENT.

Hope i am clear,

Thanks
