Hi Satish
Use FM : COM_PRODUCT_UI_GETDETAIL ,
here in the IMPORT structure IS_PRODUCT pass : product_id , product_type and logsys ( you can get product_type and logsys from table comm_product or you can even hard code them if you are sure about the product type and for logsys if the product is made in crm then the logical system id of crm if it is coming through ECC then logical system id of ECC.
and also pass these flags as X : ( IV_READ_DB_VALUES , IV_ALL_SETTYPES , IV_ALL_INTERLINK , IV_ALL_UI_ELEMENTS ).
