11060   *                         AND MAKTX = WA-MAKTX.
11070   *                         AND V_BPMNG = WA-V_BPMNG
11080   *                         AND V_BAMNG = WA-V_BAMNG

11150     ENDLOOP.
    >     MODIFY YMATPRICNG FROM TABLE WA.
11170     COMMIT WORK.

Answer 1

Hi,
I am deleting the first record which are already existing b'z I want only latest value update corresponding plant and material.
And I had declared WA as a internal table type of ymatpricng table only.And again If put up few record to selection screen via material no,It update successfully.
Only thing is that why it get cancelled with thsi dump showing that nametab and abap/4 is not consistent or buffer is out of time.
The problem has arisen because, within the database interface,
one of the data buffers made available for the INSERT (UPDATE)
is longer than the maximum defined in the database.
On the other hand, it may be that the length in the NAMETAB
does not match the maximum length defined in the database.
(In this case, the length in the NAMETAB is longer.)
