Validating metadata and RFC servers

Data loading requires validation of the metadata for each data file with the current configuration of the transfer structure for the InfoSource. The RFC Server does this as follows:

1. Each row in the metadata file is compared with the relevant row in the transfer structure to ensure parity of the metadata.
2. Metadata anomalies are reported on the status bar in the SAP BW InfoPackage scheduler, and the process aborts. The RFC Server returns to a wait-state.
3. If the metadata passes the validation test, and the data load completes successfully, a "Data requested" message appears on the status bar of the SAP BW InfoPackage scheduler, indicating that the data is loaded successfully.
