Comparison of the data extraction methods
There are two different possible ways to extract data: using existing SAP® standard components (RFC function module RFC_READ_TABLE), which already exist on the SAP® system, or using SmartExporter SAP® components.
To use the full scope of SmartExporter functionality the installation of the SmartExporter SAP® components is required.
The following table contains a comparison of the different extraction methods:
| SmartExporter SAP® components | SAP® standard components | |
|---|---|---|
|
Also records that are not available in a sorted order can be extracted correctly. |
|
