Hi

<b>What Are Functional Specification in SAP?</b>

To speak at macro level that is at projet 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. Elsewhre organizations combine these two documents into a single document.

The Functional Specification describes the features of the desired functinality.. 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 developement.

The Functional Specification defines what the functionality will be of a particulat 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, that is detchnical developement process.

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

At the consultant level the functional spects are preapred by functinal consultants on any functionality for the purpose of getting the same functinality designed by the technical pepole 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 -

😎 Future Impact & Change Assessement

9) Functional Design (Module Wise)

10) Risk Assessement

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

Note * This documents are preapared in Vanilla SAP Standards -- Things differ from one implementation to another, and it always depends on the type of business which is opting for SAP.

<b>Functional Specs For Some Payroll Report</b>

What is the proceedure to write functional specs for some report?

My client want me to write one for some payroll report. How should I proceed onto this matter?

A functional spec should theoriically mean that the ABAPer should be able to take the design document you have prepared, go and sit in a dark corner of the office and build the whole report..... this rarely if ever happens, but I think thats the theory.

When you write a functional spec, you are meant to be turning the clients requirements into a design document that a techo can then build from.

Some of the things you may want to think about are:

Report logic - What information is the report trying to get, what logical links are required to link the data together - like master data and payroll data, and org mgt data, and how should this be linked, an important bit to remember here is the time selection, do you want all the data in the system, or only the data relevant on the day, or over a month etc.

Selection screen - What fields are required as selection options

Authorisations - Should the report check the 'runners' authorisations and tailor the output accordingly

Output - What fields are required to be output, in what order, in what file type, for example this could be a text file, or just out to the screen of the runner.

Error handling - What should the report do when it encounters a problem eg what scenarios would constitue errors - what should happen etc.

Test mode - does the report require running in test mode prior to a file being produced?

Functional specification: The Functional Specification is a comprehensive document created after the Software Requirements Document. It provides more details on selected items originally described in the Software Requirements Template. Elsewhre organizations combine these two documents into a single document.

Functional specs is like a templeate document, hence it will be same whether it is AR or AP or CCA. Basically functional specs is a document which explains the requirements with technical details, so that technical consultant or any other person can read and understand what is the background of the report or an extension done in SAP.

The Functional Specification describes the features of the desired functinality. 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 developement.

The functional specs should have the following details:

Background: Information why this report is required and Business process involved in that.

Selection Parameters: This should what fields should be selection fields, which are optional and which are mandatory etc.

Layout of the report: What information is required in the output of the report. This should also indicate the technical names - Table and field names from where the data needs to be fetched.

Detailed Description: This should explain the logic of the report - what calculations needs to be done etc.

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

It also contains the data regarding change history, if any.

Functional Spec is mainly prepared for the purpose of developing the new reports (this happens only when SAP standard report not achieve the client purpose) using the ABAP Program. for ABAPers you need to give the details of the Tables , Fields and the logic how to pick the value and get the report.
