Hi,

please compare the order of the structure ty_vbap with the SELECT-statement.

In the SELECT-statement the 4th element is MATKL, but in the structure definition this is the field ZMENG. This does not fit together regarding the data type, that's why you receive this error message.

One possible and easy solution would be to use INTO CORRESPONDING FIELDS OF TABLE, see here:

    SELECT vbeln,
           posnr,
           matnr,
           matkl,
           zmeng,
           werks,
           lgort,
           netpr
      FROM vbap
      INTO CORRESPONDING FIELDS OF TABLE @gt_vbap
      FOR ALL ENTRIES IN @gt_vbak
      WHERE vbeln = @gt_vbak-vbeln.

Kind regards
