The field name had no spaces.
The structure of my tabel is


Structure for table: C:\APLIC\TAXAREELECTRO\TRANSF.DBF
Number of data records: 8421
Date of last update: 08/01/2002
Code Page: 0
Field Type
1 NR_AB Character
2 DATA Character
3 ORA Character
4 DURATA Character
5 NR_AP Character
6 NR_SEC Numeric
7 IMPULS Numeric
8 SUMA Numeric
9 MOBIL Caracter
10 MINUTE Numeric
11 TARA Character
12 FAC Character


It is posible that error apears because one field name is caled data and minute , and that is keyword in vfp ?
