QM NOTIFICATION RAISE_EXCEPTION ERROR

I have implemented the badi NOTIF_EVENT_SAVE.

The error is :

RAISE_EXCEPTION

Exception condition "OTHERS" raised.

Program                     SAPLIQS1

Include                       LIQS1F10

Row                           306

Module type               (FORM)

Module name             MSG_STORE

In this the function module ISQ1_MSG_STORE returns sy-subrc = 4 which raises the Exception.

I have tried to debug the standard code as well.

In the standard code there are two tables ITAB_JEST AND ITAB_JOST which get cleared for no reason, the dump is due to these tables getting cleared.

If I remove the badi code, I dont get any dump.
