MWST condition type tax classification of material

Question

Hi,
we modified one user exit to change forcefully of tax classification of material in user exit MV45AFZZ  .
here code is working fine but later it is changing to 1 instead of 2 while changing the sale order .
IF sy-tcode = 'VA01' OR sy-tcode = 'VA02'.
      IF vbak-landtx EQ 'DE' AND vbak-stceg_l EQ 'DE'.
        LOOP AT xvbap.
          SELECT SINGLE matnr INTO w_half_tax_mat
          FROM   zhalf_tax_mat
          WHERE  matnr EQ xvbap-matnr      AND
                 valid_from LE xvbkd-prsdt AND
                 valid_to   GE xvbkd-prsdt.
          IF sy-subrc EQ 0.
            xvbap-taxm1 = '2'.
            MODIFY xvbap.
          ELSE.
            IF xvbap-taxm1 = '2'.
              xvbap-taxm1 = '1'.
              MODIFY xvbap.
            ENDIF.
          ENDIF.
        ENDLOOP.
      ENDIF.
      ENDIF.
suggest me how to approach.

Hi,
You wont find any table for tax classification maintained in sales org-1 of material master.
we maintain this while config in OVK4- which will store in Table:TSKM.
based on tax category this tax classification called in material master.
if you chek tax class in sales org-1. it shows some table structure.
it wont store in any table.
all the fields which is there in structures called from some other tables- wont have memory to store the records.
hope it helps
