Development

Ingenious and successful SAP ABAP
I have the privilege of an ABAP developer last 9 years and IT industry as a programmer for 12 years and now a ABAP technical expert and development manager for 12 SAP implementations, I came across different working patterns of a developer ABAP professional. During this time, I met some programmers ABAP, which were very good with technical aspects and also some that were excellent ABAP development consultants who can all aspects of a management company SAP development project or a custom development, implementation or Badi improvement project. Remember that a technical expert in SAP that are critical to a project responsible for realizing the vision of SAP customer’s business processes. I think it’s very important to many aspects of programming languages in a project to implement SAP to learn and apply some guidelines that can make an SAP ABAP professional very successful in his career.

Steps to an Efficient SAP ABAP Programmer or SAP Technical Team Lead

1. Review Business Requirements and Functional Specification Writing
The first part of an ABAP development project start the meeting with end users or business experts and understand the business requirements to be implemented in the SAP system during the realization phase. The best approach is to hold workshops for all business needs to collect. Make sure any function of SAP consultants who are involved in the meetings. After all business requirements are gathered, is a functional SAP consultant or business expert to write a detailed functional specification. Review the functional specification until the document has all the details, different business scenarios and expected goals clearly defined. A well defined functional specification should contain UML diagrams and test scenarios. It is important to an official signoff on the functional specification before proceeding with the design and development.

2. Review ABAP Development Standards
Ideally, SAP Project Lead or ABAP Development Manager, created a document of programming standards and guidelines. Review this document for you to follow the naming conventions for function modules, classes, dictionary objects, software components, name spaces and proxies (if using SAP XI / PI), an input program and the parameters output, etc., for just a few. Following the directions for the project to maintain a consistent approach to coding and also helps other functional and technical analysts to read and debug your code. ABAP objects naming should begin with Z or will be migrated to SAP production system and Y, or it will not be migrated to the production system.

3. Write and review test cases

The test case documents are written by business experts and SAP functional consultants in most SAP implementation projects. But on some SAP implementation projects a programmer may need to write test cases. Before writing a test case with depth evaluation of the functional specification document and written test with business users or functional consultants for review. Make a sign-off, as mentioned in most steps in this article. If ABAP Development Manager for a variety of SAP implementation projects, has been my goal for my team motivated and always the team to any change in the volume of development tasks. After a sign-off on each phase of SAP custom development or enhancement tasks always helps the SAP implementation team and project management team in sync, which is vital for the complete implementation of SAP and within budget.

4. Write and review technical specifications of the project
Read the functional specification and a list of all the objects needed to develop the functionality required to implement the SAP system. The first step is to draw a flow chart and review of technical experts and businesses. The technical design document is a technical view, the list of objects from the database again, ABAP objects that can be reused, a data model and class diagram (using ABAP OO classes). It is highly recommended for an initial prototype of the insurance system (Development system, if no safe system SAP is available) so that, if development is done is complex or if the final delivery is not well defined. You should review your prototype with functional experts and business users. Make sure that the signs ABAP team leader or manager Prototyping. If the effort required for the task of ABAP programming is not complete proposed and approved by senior management of the project, then that would be a good time to evaluate the development schedule and approved.

5. Realization of the Specification – ABAP Development
During this step, you create objects to the development and implementation of code in the SAP development system. Before you begin, as a prototype system was conducted in the sandbox, then analyze the prototype and design specification. Remember that the quality and reusability of existing ABAP objects are more important than in strict accordance with design specifications. Determine which existing dictionary objects can be reused for this topic. If new dictionary objects or classes must be made of these objects can be extended and reused for other tasks to ensure that development initiatives. It may require an extra effort to objects that are developing reusable and flexible. This effort once and for building reusable ABAP objects during a construction project can save a lot of work for programming similar objects that could use objects ever built. Review your approach with a team leader or manager SAP technical development of your project before you depart from the technical specifications for designing and implementing their own ideas. If you are involved in SAP XI (now Process Integration) tasks or services related to creating the company, then this is the best area where you can reuse existing objects. Read the message types that already exist in your SAP business unit to see if all messages can be extended with new fields. Talk to the team leader or the communication should be synchronous or asynchronous before you generate proxies.

6. SAP Best Practices Development
SAP ABAP (or Java if working on SAP Netweaver) development best practices should be followed during the development cycle of the project. Although this aspect depends on its technical project manager, I personally have kept a checklist for developers in my team at all projects and is a huge success in providing high-quality output on all development tasks. Here are some best practices, adapting feather in your project. Make sure you meet all the conventions, as described in the programming needed for your implementation project. Comments in your code, someone can easily understand your programs. This is especially useful when working in large teams and multiple people use the same objects. Be sure to check the operations of the user’s authorization or if you’re building Web user interfaces that require human interaction. Make sure you do not have ABAP code segments that could take a hit on performance like nested loops, nested SELECT statements (use views if desired), excess database commits (persistent objects or alternative buffer may be a good choice), etc. symbols. Field is a great advantage when it comes to processing internal tables and also variables with unknown types of data are resolved at runtime. Field symbols are similar to the concept of using pointers in OO programming landscape. Make sure that all exceptions are handled and error messages are communicated accurately to the end users. If the ABAP programmer should be well accepted by now that the short-term deposits should not be OK to occur. All they occur in unknown scenarios specific case, the short dumps should be set.

7. ABAP code reviews and performance
If the ABAP programmer you should test your code, after all possible scenarios. See the final results are identical to those expected in the test cases documented. Perform analysis of ABAP runtime to check the performance of your code. Ask for suggestions from your team leader or technical manager on how to code to improve performance if you have a red flag during the analysis of the runtime. Plan a formal code review with your mentor or a senior ABAP developer once the development is completed and tested by all responsible developers. Make any revisions and enter your code against the desired output as documented in the test scripts. Remember that code reviews can not find errors in your lineup, but will only give you a better developer ABAP and consistency.

8. Documentation
Be sure to write a final list of documents with the functionality or improve later. Include pictures whenever possible. Preparation of documentation in mind that a user unfamiliar with your stock can read the document and test the functionality. Include contact information in this document so that users easily reach the SAP technical team for any questions.

9. User Acceptance Test
Now that your ABAP coding is completed and reviewed by experts, it’s time for business users to a formal acceptance testing of the user to perform. UAT testers will check the output of the requirements of business processes and the suggestions or changes to functionality delivered. Upon completion of these corrections or adjustments you need to ask for formal approval on functionality.

10. System testing and migration to SAP Production System
quality assurance engineers to test the functionality in SAP QA environment to verify that everything works in your delivered functionality as tested during user acceptance testing. Furthermore, any problems in transporting the objects through SAP ABAP will be identified and addressed during this step. If no problems are found, then the transport will be approved to be migrated to SAP production system to the next transport cycle.

You just learned how efficient SAP ABAP Developer or by saying a high quality Senior ABAP expert right to write the specifications to carry out its implementation in the production system. Use this article as a guide, because there are many more aspects to improve yourself to a good ABAP programmer is not possible in a short article like this to be. You can always contact me with any suggestions or ideas that you can ask for your SAP implementation.
