I use stpapi calls to automate the sales order session. (tdsls4101m000.) BaaN iv c4 with supply chain.
I fetch data for the session from the database.
It works fine for 6 or 7 records.
when the number or records exceeds 8 or 9 it throws me this error at runtime.
this is stored in event viewer.

bdberrno 509 (Bad memory cursor; bad table pointer specified)
Message Exception C0000005 (Access violation)
1:000061f4

Can anyone tell me why this error occurs?

thanks in advance.

As someone suggested on these boards, you can often fix these types of problems by programming the session open and close for each record. I know that is not the best performance solution, but it seems to reset things properly each time. You can try it for your problem and see if it helps.

I believe this is a problem with the stpapi code, and needs to be fixed by Baan.

I am starting the session and after that I close the session each time. so It works fine for less number of records. but when it exceeds 7 or 8 it gives me runtime error..

problem was with the porting set. when upgraded to the latest porting set, the problem got solved.
