Error in TM doc save with /BOBF/IF_FRW_CONFIGURATION~GET_NODE

Hello Experts

Need help. When we try to create and save document e.g. Freight Order, system is giving dump with below details.

Can anyone help identify the nearest cause of the issue?

There is no enhancement done on this part of code.

"ASSERTION_FAILED" " "

"/BOBF/CL_CONFRT_COMPLETE======CP" or "/BOBF/CL_CONFRT_COMPLETE======CM00D"

"/BOBF/IF_FRW_CONFIGURATION~GET_NODE"

The detail of dump log is as

    1 METHOD /bobf/if_frw_configuration~get_node.

    2

    3   READ TABLE mo_conf_sh->mt_node

    4     WITH TABLE KEY node_key = iv_node_key

    5     INTO es_node.

    6   IF sy-subrc NE 0.

>>>>>     ASSERT sy-subrc = 0.

    8   ENDIF.

    9   ms_last_node = es_node.

   10

   11 ENDMETHOD.

Earliest help will be appreciated with points.

Thanks

Amol
