User exits
User exits are standard gate ways provided by SAP to exit the standard code and we can
write our own code with the help of ABAP workbench. its not new functionality which
we are trying to build in sap but its slight enhancement within the same code.
Gap analysis
Gap analysis is start point of Realization and once blue print is finished we have to find
the realization of sap system for client requirment and there will be certain gaps when
compared to system fit.
Gaps can be closed either by re -engineering of business process to fit with SAP
we have to use USER exits in case of smal l deviations or complete enhancements with the help of ABAP to fit with the SAP system
