Hi Viren,
I do not think there is a relationship between Product and Business Transaction. The easiest way is to write a query as mentioned below:
data: lt_guids type crmt_object_guid_tab,
IF lv_product IS NOT INITIAL.
SELECT DISTINCT header FROM crmd_order_index INTO TABLE lt_guids
WHERE process_type_ix IN ('TA', 'ZTA' )
AND product_id eq lv_product.
ENDIF.
You can also add Inner Joins with CRMD_ORDERADM_H and CRM_JEST (for status) tables to add other restrictions.
Thank you
Anji
