[pritesh_bamane]

I have written the below code but thats allowing only pdf attachments to be downloaded. Kindly suggest.

CODE:

P_BO_ID = WA_EKPO-EBELN.

LO_IS_OBJECT_A-INSTID = P_BO_ID.
LO_IS_OBJECT_A-TYPEID = P_BOTYPE.
LO_IS_OBJECT_A-CATID = 'BO'.

WA_REL-SIGN = 'I'.
WA_REL-OPTION = 'EQ'.
WA_REL-LOW = P_RELTYP.
APPEND WA_REL TO LT_REL.


CALL METHOD CL_BINARY_RELATION=>READ_LINKS

IS_OBJECT = LO_IS_OBJECT_A
* IP_LOGSYS =

IT_RELATION_OPTIONS = LT_REL

Loop at LT_LINKS INTO WA_LINKS.
clear: document_id, DOCUMENT_DATA,OBJECT_CONTENT,OBJECT_CONTENT[].
DOCUMENT_ID = WA_LINKS-instid_b.
