Link between Material Document number & Accounting document number

Question

Hi All,
For material document there is a corresponding accounting document number generated.However this is not the rule in all cases.
Where is the link between the two(Material Document & Accounting Document) ?
In other words i want to list those material documents only, for which accounting documents are generated.

Answer 1

STEP 1
SAP query way to extract your information.
Create an infoset SQ02 with a single table MKPF. (include key fields in the field group)
Step 2
From Extras
Create an additional field called zawkey (like bkpf-belnr) which will concatenate the MM document number MKPF-MBLNR and MKPF_MJAHR. The sequencing shall be number 1.
You may use this code below and paste also (this needs authorization as well)
data: zzawkey like bkpf-awkey.
clear: zawkey, zzawkey.
concatenate mkpf-mblnr mkpf-mjahr into zzawkey.
zawkey = zzawkey.
Add another field called ACCDOCNO (accounting documnet number) with sequencing number 2 with following code.
data: zaccdocno like bkpf-belnr..
clear: zaccdocno, accdocno.
select belnr from bkpf into zaccdocno where
  bukrs = ccode and
  GJAHR = MKPF-MJAHR and
  awkey = zawkey.
endselect.
accdocno = zaccdocno.
Step 3
Include the additional fields  into the field group.
Step 4
Click on the selection tab and create a parameter called ccode with a description Company Code and  against
LIKE    BKPF-BUKRS 
Extras  OBLIGATORY 
Step 5
Click on the selection tab and create a seelction criteria pdate with a description Posting Date for the field MKPF-BUDAT
Extras  OBLIGATORY 
Step 6
Save, Generate and assign the infoset to a user group.
Step 6
Create a SQ01 query under the usergroup with all the fields in the infoset. and Execute. Enter a company code and one date of a working day where you expect material transactions.
The result will be all the material documents and their corresponding accounting documents, if available. If you want to see only those material document that do not have corrsponding accounting documnet, then while you are in the selection screen say accounting document number is not equal to blank.
