Wrong entry in the table stock transport requisition index EBUB

Question

we have 2 plants 7080 and 6501, they belong to different company codes.
in plant 6501, after MRP run a PR is created for material 420000064,we can see entry in table EBAN as below.
Client Purchase Req. Requisn Item Document Type Doc. Category Materaial   plant
500    0014381981    00010        NB            B    000000000420000064  6501
but several days later, we found a PRqRel item appear in stock/requirement list of material 320003192 in plant 7080, and we also found entry in table EBUB:
  Client Material             Supplying Plant Purchase Req. Requisn Item
  500    000000000320003192   7080            0014381981    00010
this is wrong and may cause wrong goods issue, we checked a lot to find the root cause but failed.
we have doubt that it is number range issue, but after checking we don't think so.
In OMI2, here is the interval.
No. From To current number
01 0010000000 0019999999 10352698
please kindly help, what could be the possible cause of this error, any suggestion will be appreciated.

That error is supposed to be fixed in versions 4.0 and later I think you'd have to delete the unnecessary entries from EBUB using the program from the note 130136, you may have to search more SAP notes:
Report ZKOREBUB
*& Title: deletes EBUB which is not necessary                          *
REPORT ZKOREBUB .

INCLUDE FMMEXDIR.

SELECT-OPTIONS: S_MATNR FOR EBUB-MATNR,
                S_RESWK FOR EBUB-RESWK.

                   AND   RESWK IN S_RESWK.
  CLEAR DEL_FLAG.
  SELECT SINGLE * FROM EBAN WHERE BANFN EQ EBUB-BANFN
                            AND   BNFPO EQ EBUB-BNFPO.
