RFC Server Programs Sending/Receiving Internal Tables  Locate the document in its SAP Library structure

In RFC functions offered by RFC server programs, all importing and exporting parameters must be defined and also all internal tables as described in RFC Client Program Transferring Internal Tables and RFC Client Program Receiving Internal Tables" in Programming Examples, but it is not necessary to call ItCreate.

This will be done automatically by the RFC library. After an RFC function is ended, the RFC library will free the storage for all internal tables used in this function.
