Dear Experts

I have four dbf's as follows

Fixbook, index bill_no
Vouchers, index vou_no
Vou_sum, index vou_no
Fixbill, index bno

Data in all dbf's is about similar.
To delete a record from all dbf's I use following command
But the problem is when I issue command the data from only first dbf, Fixbook, is deleted and in other theree dbf's remain same as previous.

In Vouchers.dbf there is double entry of any vou_no, DR & Cr. and other
three dbf's has single entry.

Please enable my codes to delete same vou_no from all four dbf's.

Thanks in advance

SELECT FIXBOOK
SCATTER MEMVAR
ACC_CODE2 = m.ACC_CODE
CODE2 = m.ACC_CODE
DATE1 = m.FIX_DATE
VOU_NO2 = m.VOU_NO
VOU_NO1=THISFORM.TEXT12.VALUE

DELETE FOR BILL_NO=VOU_NO1
PACK

SELECT VOUCHERS
DELETE FOR VOU_NO=VOU_NO2 .AND. VOU_TYPE='PR' .AND. DATE=DATE1
PACK

SELECT VOU_SUM
