    4. In the Properties panel, on the General tab, enter a name and description.
    5. Click the Source tab and configure the source details.

    7. Note: You must link the DOCNUM port of the mapplet to the source transformation. The DOCNUM port represents a unique number for each IDoc and the SAP system does not accept inbound IDocs without a unique document number.
