    DFD is called as DataFlow diagram which is one of the tools used for process mapping in Structured Systems approach. It is similar to Object orientation class diagrams or ER diagrams in database mngt systems.

    DFDs mainly concentrate on the datainflow, dataoutflow and the processing. The inflow and outflow are known to us but the processing logic is Blackbox to the user.

    There are various tools available in market to draw dataflow diagrams based on the input details.

    Gap analysis is nothing but the functionality which is asked by the user but not provided by SAP. As is and To be fit will lead to Gaps.

    It is possible to draw DFDs for the gaps we get, though in ERP realm, DFDs are passe.

    You can learn more about DFDs in googlesearch. It is huge that it cant be just explained here, as it talks about various kinds of data and processing.

    Hi,

    A through gap analysis will identify the gaps between how the business operates ad its needs against what the package can can't do. For each gap there will be one of three outcomes which must be recorded and actioned, GAP must be closed and customised software can be developed close the gap, GAP must be closed but software cannot be written therefore a workaround is required, GAP does not need to be closed.

    In simple terms: Gap means small cracks. In SAP world. In information technology, gap analysis is the study of the differences between two different information systems or applications( ex; existing system or legacy system with Client and new is SAP), often for the purpose of determining how to get from one state to a new state. A gap is sometimes spoken of as "the space between where we are and where we want to be." Gap analysis is undertaken as a means of bridging that space.

    Actual gap analysis is time consuming and it plays vital role in blue print stage.
