BAPI BAPI_ALM_NOTIF_CREATE: BTPLN(Affected Func location issue)

Hi All,

I am using BAPI BAPI_ALM_NOTIF_CREATE to create a notification.

In Tx IW21, I can see a field called BTPLN( Affected Functional location). But I can not see any specific field for this one in BAPI.

If you know, could you help let me know which field should I try.

Many thanks

Shirin
