Sahu,
It appears that the REFERENCE info in BAPI_ALM_NOTIF_CREATE only creates a document-flow reference, not create a new notification with reference to another.
Here's what I entered to test this BAPI:
- NOTIF_TYPE = M1
- NOTIFHEADER-REFOBJECTTYPE = BUS2038
- NOTIFHEADER-REFOBJECTKEY = 000800000741
- NOTIFHEADER-REFRELTYPE = do not enter any value
- NOTIFHEADER-FUNCT_LOC = any functional location
- NOTIFHEADER-SHORT_TEXT = any short text
You could also take a look at function module IQS0_CREATE_NOTIFICATION.
