BAPI_SLSRVAPS_DELMULTI passing parameters to TABLES

Hi APO gurus,

I am using BAPI_SLSRVAPS_DELMULTI to delete transaction data for /SAPAPO/RLCDEL.

My question is how to pass the parameters to this BAPI to achieve the functionality.

Logical system, etc import parameters, I am fine.

Passing values to Tables, is not clear to me.

1)ORDER_KEYS  => I have order number. How to get ORDER_ID

2)ATP_REQUEST_KEYS => I have order number. how to get Order_id, item_n, user_GUID

Thanks for your help.

I have searched in SCN forum on this, but not found sample code/ details on passing values to the tables.
