Initial Table Load in SAP Versions < 7.10

The following article shows how to handle the initial table load for delta extractions using the Table CDC extraction type. The article applies in the following situation:

  • The Table CDC extraction type is run on SAP releases < 7.10
  • The option Extract table on first run (Delta initialization) is activated.
  • The delta initialization takes longer than the maximum processing time specified in the SAP profile parameter rdisp/max_wprun_time.
  • The extraction aborts with an error message, e.g., ERPConnect.ABAPRuntimeException: RfcInvoke failed(RFC_ABAP_RUNTIME_FAILURE): TIME_OUT - Time limit exceeded.

Note

The custom function module /THEO/READ_TABLE used by the Table CDC component to extract the table does not support background mode on SAP releases < 7.10. The background mode avoids the timeout mentioned above.

  1. Create a Table CDC extraction. Make sure the option Extract table on first run is deactivated.

  2. Run the Table CDC extraction to initialize the delta extractions. This ensures that no data is missed between table extraction and delta initialization.
  3. Create a regular Table extraction using the Table extraction type. Make sure to select an SAP standard function module, e.g., RFC_READ_TABLE.
