Hi Chris,
Thanks a lot. I found the standard eval path ORGEH suffice my purpose.
Below code is working fine.
CALL FUNCTION 'RHPH_STRUCTURE_READ'
EXPORTING
plvar = '01'
otype = 'O'
objid = ls_pathroots-objid
wegid = 'ORGEH'
BEGDA = SY-DATUM
ENDDA = SY-DATUM
PUP_INFO = 'X'
WITH_STEXT = 'X'
TDEPTH = 4
TABLES
stru_tab = lt_stru
EXCEPTIONS
CATALOGUE_PROBLEM = 1
ROOT_NOT_FOUND = 2
WEGID_NOT_FOUND = 3
OTHERS = 4
Thanks
Arindam
