2lis_02_scl or 2lis_02_itm - goods receipt/invoice receipt number

Hi Gurus,

there is a field:

BUDAT - Posting date of goods receipt/invoice receipt for purchase order; Table: EKKO/EKBE

in 2lis_02_scl and 2lis_02_itm Data Sources.

As I can see, for every Purchase Order Item I get three records:

- one record for the last Invoice Receipt (with Posting date of invoice receipt in BUDAT field)

- one record for the last Goods Receipt (with Posting date of goods receipt in BUDAT field)

- one record for something else.

Do I understand it well? What is the third record?

I would to get Material Document Number, that is, Invoice Receipt Number for the first record and Goods Receipt number for the second one. How can I make it?

Regards,

Dorota
