Before you upgrade the connector to enable the ALE Module to process IDocs, you must complete the processing of current files in the event and WIP directories. Also, check the archive directory for failed and unsubscribed events.

%CROSSWORLDS%\connectors\SAP\ale\events %CROSSWORLDS%\connectors\SAP\ale\wip
