SAP EXPORT_BUFFER_NO_MEMORY error

Some Qlikview extracts are abending on the SAP side with the message "EXPORT_BUFFER_NO_MEMORY".
The error points to the parameter "rsdb/obj/buffersize".

In Qlikview the error appears as :


Custom read failed
SQL SELECT *
FROM KNA1



Running RSPFLDOC via SE38 shows the parameter values:

Appl.area: General system
Parameter Type: Integer Value
Changes allowed: Change permitted
Valid for oper.system: All
Minimum: 16
Maximum: 256,000
DynamicallySwitchable: (blank)
Same on all servers: (blank)
Dflt value: 4096
Profile value: 20000
Current value: 20000

Has anyone else encountered this error?
How do others have "rsdb/obj/buffersize" configured?
Thanks,
Ben

Did you try adjusting the packetsize ? Default is 20k. I had the same problem and I took mine down to 5k and it's working fine now.

Hi Sunil,

Which parameter did you amend in the QV SAP Connect string and to what value please?

We are having same issue with QV 10 SR1 using SAP Connector 5.50 SR3

Thanks

I add following extra parameter in connection string to extract cluster table.

TimeOutBatch=1800;

TimeOutFetch=3600;

TimeOutStartBatch = 4200;

PacketSize = 5000

I have different connect strings based on what I am extracting from SAP. For example if I am extracting VBAK / VBAP data I use a smaller packet size (5000), otherwise I used the default.
