SAP Connector 3.0 - RFC_READ_TABLE errors

[#1]

Hi All,

I'm using the new nCo 3.0 to get access to tables via the RFC_READ_TABLES function.

I am able to access the tables and download data OK, however i sometimes get these error messages

'RfcCompressor: CsRDecompress failed with rc = -22'. (normally happens towards the end of a table data extraction)

'End mark of RFCID.TableContLZ not found.' (occurs while trying to invoke the RFC_READ_TABLES function, however occurs randomly)

I'm grabbing the data from tables at 50,000 rows at a time, and have set the below parameter values.

tableRead.SetValue("QUERY_TABLE", Trim(dr("saptbl")))

tableRead.SetValue("ROWCOUNT", GetDownloadChunkSize)

tableRead.SetValue("ROWSKIPS", 0)

If hasFields = True Then

tableRead.SetValue("FIELDS", fieldsTable)

End If

If hasOptions = True Then

tableRead.SetValue("OPTIONS", optionsTable)

End If

Just wondering whether anyone has come across these error messages and are able to explain why they are occurring?

Regards,

I also am getting this same error when calling a function module which returns a large number of rows, RfcSerializationException was unhandled - End mark of RFCID.TableContLZ not found. Looks like something is being truncated.

Hi,

RFC_READ_TABLE function module has a lot of problems with assign statements and conversion. It doesn't support all data types. RFC_READ_TABLE function should not even exists any more in ECC6.0.

However there is an alternative function which you can use and to my experience it doesn't have the problems rfc_read_table had. Check SAP note 1175255, how to implement BBP_RFC_READ_TABLE. It is used exactly like the rfc_read_table.
