JCO_ERROR_COMMUNICATION: connection closed without message (CM_NO_DATA_RECEIVED) (tSAPTableInput)

Anonymous — Tue, 12 May 2020 00:20:13 GMT

Hello,
What should i do?

I have installed Talend Function Modules for SAP and I set the parameter "api.z_talend_read_table is true",

but I still get an error when using tSAPTableInput with 800000+ rows and 90+ columns as below

Exception in component tSAPTableInput_1 (SAP)
SAPException@4229bb3f [
errorCode=1

Looks like you try to extract data from BW System. Maybe you can try to partitionize the data by using a filter on a field and call the component tSAPTableInput per filter value in a loop. Depending on the SAP System Configuration 800.000 rows might be to much to extract it once. Or try first to get e.g. 25.000 rows by using a specific filter condition.

Otherwise you could ask the SAP Admin-Team to help to analyze this error.

hi mwinker,
Thanks for your advice
I have partitioned the data as you said.
and then I get an error like this:

Exception in component tSAPTableInput_1 (Looping)
SAPException @ 5ba3f27a [
    errorCode = 1
   , errorGroup = 104
   , errorKey = JCO_ERROR_SYSTEM_FAILURE
   , errorMessage = Unable to fulfill request for 2650 bytes of memory space.
   , errorMessageText =
   , bapiName = / CMT / TLND_TABLE
   , tableName = / BIC / B0003822000
]

Could you please test with a fixed filter to check whether you are able to extract 10.000 rows, 20.000 rows, 50.000 rows?

If a batch has less than 800.000 it should be feasible. (will take some time). Otherwise the RFC System Parameter are set so restrictive and allows smaller
data transfers only.

hi mwinker,

I tried what you suggested.
when it reaches the record to 1.5 million to extract an error occurs as below

Exception in component tSAPTableInput_1 (Looping)
SAPException@1e04fa0a [
errorCode=1
,errorGroup=104
,errorKey=JCO_ERROR_SYSTEM_FAILURE
,errorMessage=Unable to fulfil request for 2650 bytes of memory space.
,errorMessageText=
,bapiName=/CMT/TLND_TABLE
,tableName=/BIC/B0003822000
]

Please help.

Thanks
