Error encountered while inserting data into DB!!

Question:
Hi,
I'm working on SAP release 46C. I've created my own program to enter Goods Receipt data. On saving this data I populate a DB table thru the statement "Insert into DBTAB client specified values itab1".
I'm encountering a dump with the error "Invalid call to the database interface".
Can anyone point out what is the problem. I'm really stuck with this problem.
Thanx in advance.
Kalyan.
Answer:
Has ITAB1 a header line? Only this will be inserted by your statement. And has it the same structure as DBTAB?
Answer:
Hi Hans,
Itab1 is a Work Area and has the same structure as the DBTAB.
This is how I've declared the work area.
Data : begin of itab1,
include structure DBTAB,
end of itab1.
It's still giving me an error.
Thanx.
