Link between invoice number and material document number

Question

I need a way to get the list of material document numbers which correspond to a particular invoice.  Is there a way to find this information?  I am looking [looping] at table EKBE during a user exit in SAPMV60S but I need to restrict the entries by a range of (multiple) material document numbers.

It looks like you're missing a piece of code.
        SELECT SINGLE * FROM BKPF WHERE BUKRS = Z_EKKO-BUKRS AND
*                                       BELNR = EKBE-BELNR AND
                                        AWKEY LIKE X_KEYFLD AND
        CHECK SY-SUBRC = 0.
The SELECT just ends at the "AND".
Should there be another line after the "AND"?
You said you had an invoice number; why can't you use that in your WHERE clause to limit what is returned from BSEG?
What field are you using for the invoice?
I had mentioned BKPF-XBLNR before, which we use to store the vendor invoice on a PO, but what you are doing sounds different.  Are you referring to an invoice that you created?
I think that this might be in BSEG-REBZG, and you should be able to filter on this field.
Shouldn't such an additional filter give you what you want?
e.g.
if the invoice specification is a single value:
* Getting the Vendor Invoice header data
  SELECT SINGLE * FROM bseg WHERE bukrs = z_ekko-bukrs AND
                                  belnr = bkpf-belnr AND
                                  hkont = '0000416000' AND
                                  rebzg = invoice
or, if the invoice specification is a range or list:
* Getting the Vendor Invoice header data
  SELECT SINGLE * FROM bseg WHERE bukrs = z_ekko-bukrs AND
                                  belnr = bkpf-belnr AND
                                  hkont = '0000416000' AND
                                  rebzg IN s_invoice
If you are not using rebzg, then do the same against whatever field you are using.
Good luck
