UPDATE termination in VA01 transaction.

Question

Hello Experts,
   I am stuck in one place. could you please help me for the same.
I am uploding data in ZVA01 transaction using batch input session.
while uploading 82-83 line items, and save it, i am getting the error. "SAPSQL_ARRAY_INSERT_DUPREC".
i checked the error. it is from the include :LV45UF0K and this is the standard code.
the code is given below :
FORM KONV_BEARBEITEN.
  CHECK: FKONV_GEAENDERT NE SPACE OR
         VORGANG = CHARH.
  IF VORGANG NE 'H'.
    DELETE FROM KONV WHERE KNUMV = VBAK-KNUMV.
  ENDIF.
  LOOP AT FXKOMV.
    FXKOMV-MANDT = VBAK-MANDT.
    FXKOMV-KNUMV = VBAK-KNUMV.
    MODIFY FXKOMV.
  ENDLOOP.
  INSERT KONV FROM TABLE FXKOMV.
  IF SY-SUBRC NE 0.
    MESSAGE A100 WITH 'KONV' SY-SUBRC.
  ENDIF.
ENDFORM.
. error is : it is try to insert the duplicate entry in the KONV table.  i dont know why the error is comming and in which code the error is.
i splitted the line items into 2-3 parts and then uploaded, this time it is uploading properly.
i want to upload all line items in one time (82-83 line items).
could you please suggest, what is the error ?.
Thnaks in advance.

Hi,
the key for table KONV contains five fields:
MANDT
KNUMV
KPOSN
STUNR
ZAEHK
The code you included fills the first two and deletes the entries for these values first. So the problem is not in that value. The other three values are:
KPOSN     Condition item number
STUNR     Step number
ZAEHK     Condition counter
Where the last one is added just to make the whole key unique. Chances are that this field is not filled correctly in some user exit making the transaction fail at the point you indicated. Check in the dump if you can find out what the values are in this table and which ones generate the duplicate key error. Also investigate if the FXKOMV table is changed in user exits or custom pricing routines and check that code for bugs. It will be pretty hard to debug it all since you get the problem in BDC processing...
Good luck,
Gert.
