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:

• Table CDC extractions run on SAP releases < 7.10
• The option Extract full 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.

Recommended Workflow

To do the initial table load and prepare delta updates:

1. Create a new Table CDCextraction. Make sure the option Extract full table on first run is deactivated.
   
2. Run the Table CDC extraction to initialize delta extractions. This ensures that no data is missed between table extraction and delta initialization.
3. Create a new Table extraction.
4. Select an SAP standard function module for the extraction, e.g., RFC_READ_TABLE.
   
5. Run the Table extraction.

The initial load of the table is completed without timeouts.
