    dear suresh

    Functional Spec: FS is a document written by the functional guy to communicate to the ABAPer, to say what development needs to be carried out and what are the tables and fields involved. The basic reason for a functional spec would be that of documentation and reference and importantly the technical guys wouldn’t really know the business process but only the tables and fields involved. So the functional guy communicates the business requirement in technical way through a functional spec. Features of a FS would be that it will have a version number which would change depending on the modifications made to that particular object there after. There would be a pseudo logic which outlines what needs to be done for data extraction, tables and fields to be used, validations, testing info .,

    A functional spec is a document which provides the logic to carry out the development. This document contains logic to be followed & the table from which the data is to be picked. It also contains details of which are the connecting table & how the fields are to be mapped

    what are Functional Specification in SAP?

    To speak at macro level that is at project manager or at senior levels. The Functional Spec (Specification) which is a comprehensive document is created after the (SRS) Software Requirements Document. It provides more details on selected items originally described in the Software Requirements Template. Elsewhere organizations combine these two documents into a single document.

    The Functional Specification describes the features of the desired functionality.. It describes the product's features as seen by the stake holders, and contains the technical information and the data needed for the design and development.

    The Functional Specification defines what the functionality will be of a particular area that is to be precise a transaction in SAP terminology.

    The Functional Specification document to create a detailed design document that explains in detail how the software will be designed and developed.

    The functional specification translates the Software Requirements template into a technical description which

    a) Ensures that the product feature requirements are correctly understood before moving into the next step, which is technical development process.

    b) Clearly and unambiguously provides all the information necessary for the technical consultants to develop the objects.

    At the consultant level the functional sects are prepared by functional consultants on any functionality for the purpose of getting the same functionality designed by the technical people as most of the times the functionalities according to the requirements of the clients are not available on ready made basis.

    Let me throw some light on documentation which is prepared before and in a project:

    1) Templates

    2) Heat Analysis -

    3) Fit Gap or Gap Analysis

    4) Business Process Design

    5) Business Process Model

    6) Business Change & Impact

    7) Configuration Design, which is just 5 % of Total SAP- have different names -

    8) Future Impact & Change Assessment

    9) Functional Design (Module Wise)

    10) Risk Assessment

    11) Process Metrics and Many More-- Which has impact on Business and its work flow

    rewards if it helps
