Change service order notification header using BAPI_ALM_ORDER_MAINTAIN

[aakkar]

Hello SAP community, 

We want to update header notification for an already existing service order with already created notif.

I have one service order eg: NZ12YBO00085 to which a header notification is already assigned eg :301714374 , this notification exists also in object list. what i want to do is to update header notification to another one eg: 301714338 and adding this once also to object list. i tried using BAPI BAPI_ALM_ORDER_MAINTAIN like follow: 

in table IT_HEADER , i put service order ID NZ12YBO00085 and new notif ID 301714338 

in table IT_HEADER_UP : i put service order ID NZ12YBO00085 and i put 'X' in notif number

in table IT_OBJECTLIST : i put NOTIF_NO : 301714338 and COUNTER : 0

in table IT_OBJECTLIST_UP: i put 'X' in PROCESSING_IND

But i'm getting this result, and nothing is done notif is not updated neither added to object list

I tried with COMMIT also, tried just method change without create objeect list but still nothing is changed. Could anyone help please ?

Thank you
