Profitable & Resourceful SAP ABAP Developer
ABAP / ABAP OO improvement are very essential in addressing any answer gaps, RICEFs or customized improvement on any SAP challenge. I believe it is vitally vital to know a number of totally different programming elements throughout an SAP implementation challenge and comply with sure pointers that may make an SAP ABAP skilled very profitable in your profession.
Steps for being an Environment friendly SAP ABAP Programmer or SAP Technical Group Lead
1. Evaluation Enterprise Necessities & Write Practical Specification
The primary a part of any ABAP improvement challenge start with assembly the top customers or enterprise specialists and perceive the enterprise necessities that have to be carried out within the SAP system throughout the realization section. A greatest method is to conduct workshops to collect all of the enterprise necessities. Make it possible for if any SAP operate consultants are concerned than they’re within the conferences as effectively. After all of the enterprise necessities are collected, both a SAP purposeful marketing consultant or enterprise skilled will write an in depth purposeful specification. Evaluation the purposeful specification till the doc has all the small print, totally different enterprise eventualities and anticipated targets clearly outlined. A effectively outlined purposeful specification ought to include UML diagrams and check case eventualities. You will need to have an official signoff on the purposeful specification earlier than persevering with with design and improvement.
2. Evaluation ABAP Growth Requirements
In excellent case, your SAP Mission Lead or ABAP Growth Supervisor ought to have created a programming requirements and pointers doc. Evaluation this doc so that you simply comply with the naming conventions for operate modules, courses, dictionary objects, software program parts, identify areas and proxies (if utilizing SAP XI / PI), program enter/output parameters, and so forth simply to call just a few. Following the rule for the challenge helps keep a constant coding method and in addition helps different purposeful and technical analysts to learn and debug your code. ABAP objects naming ought to start with Z if it will likely be migrated to SAP manufacturing system and Y if it is not going to be migrated into the manufacturing system.
3. Write and Evaluation Check Instances
The check case paperwork are written by the enterprise specialists or purposeful SAP consultants in most SAP implementation initiatives. However on some SAP implementation initiatives a programmer could also be required to jot down check circumstances. Earlier than writing a check case evaluation the purposeful specification doc completely and evaluation the written check case with the enterprise customers or purposeful consultants. Get a sign-off as talked about in most steps on this article. As an ABAP Growth Supervisor for a wide range of SAP implementation initiatives, my purpose has been to maintain my crew motivated and all the time cowl the crew towards any change of scope on the event duties. Having a sign-off at every section of a SAP customized improvement or enhancement duties all the time helps the SAP implementation crew and challenge administration crew maintain in sync which is a crucial to finish the SAP implementation in time and price range.
4. Write and Evaluation Technical Design Specs
Learn the purposeful specification and listing all the event objects that will be wanted to implement the required performance within the SAP system. First step is to attract a flowchart and evaluation with technical and enterprise specialists. The technical design doc ought to embrace a technical overview, listing of latest database objects, ABAP objects that may be reused, a knowledge mannequin and sophistication diagram (if utilizing ABAP OO courses). It’s extremely beneficial to have a tough prototype within the sandbox system (Growth system if no SAP sandbox system is on the market) if the event being accomplished is complicated or if the top deliverable isn’t effectively outlined. It is best to then evaluation your prototype with purposeful specialists and enterprise customers. Make it possible for the ABAP Growth crew lead or supervisor indicators off on the prototype. If effort required to finish the ABAP programming process isn’t offered and authorised by the senior challenge administration then this is able to be time to get the event estimate and timeline authorised.
5. Realization of the Specification – ABAP Growth
Throughout this step you may be creating improvement objects and implementing the code within the SAP improvement system. Earlier than you start, if prototype was accomplished within the sandbox system then analyze the prototype and design specification. Keep in mind that high quality and reusability of present ABAP objects are extra vital than strictly following the design specification. Decide which present dictionary objects could be reused for this subject. If new dictionary objects or courses must be created then be sure that these objects could be prolonged and reused for different improvement duties. It might require further effort to develop objects which can be reusable and versatile. This one time effort for constructing reusable ABAP objects throughout the course of a improvement challenge can doubtlessly save a number of work for programming related objects that might in any other case make the most of already constructed objects. Evaluation your method with an SAP technical crew lead or a improvement supervisor in your challenge earlier than deviating from the technical design specification and implementing your personal concepts. If you’re concerned in SAP XI (now Course of Integration) associated duties or creating enterprise providers then that is the most effective space the place you possibly can reuse present objects. Evaluation the message sorts that exist already inside your SAP enterprise unit and see if any present messages could be prolonged with new fields. Evaluation with the crew lead whether or not the communication must be synchronous or asynchronous earlier than you generate proxies.
6. SAP Growth Greatest Practices
SAP ABAP (or JAVA if engaged on SAP Netweaver) improvement greatest practices must be adopted all through the event lifecycle of the challenge. Though this facet will depend on your challenge technical supervisor, I personally have maintained a guidelines for builders in my crew on all initiatives and it has been an incredible success in delivering prime quality output on all improvement duties. Listed here are just a few greatest practices price adapting in your challenge. Verify whether or not you adhere to all naming conventions as described within the programming requirements set in your implementation challenge. Embody feedback in your code to permit another person to simply perceive your packages. That is notably useful once you work in giant groups and a number of folks work with similar objects. Guarantee that you’ve got examine for person authorization in case you are constructing transactions or net user-interfaces that may require human interplay. Verify that you simply wouldn’t have ABAP code segments that might take a success on efficiency like nested loops, nested choose statements (use views if desired), extra database commits (persistent objects or buffering alternate options could also be choice), and so forth. Discipline symbols are an amazing asset in relation to processing inner tables and in addition variables with unknown knowledge sorts which can be resolved at runtime. Discipline symbols are similar to idea of utilizing pointers in OO programming panorama. Verify if all exceptions are dealt with and error messages are communicated precisely to the top customers. As an ABAP programmer it must be effectively accepted by now that brief dumps shouldn’t be OK to happen. All these do happen in unknown particular case eventualities the brief dumps must be fastened.
7. ABAP Code Evaluations and Efficiency
As a ABAP programmer it is best to check your code upon completion for all attainable eventualities. Confirm that finish outcomes are similar as that anticipated within the documented check circumstances. Carry out ABAP runtime evaluation to examine for efficiency of your code. Search strategies out of your technical crew lead or supervisor on find out how to enhance code efficiency for those who discover any crimson flags throughout the runtime evaluation. Schedule a proper code evaluation together with your mentor or a senior ABAP developer as soon as the event is accomplished and examined by all accountable builders. Make any revisions and retest your code towards the specified output as documented within the check scripts. Keep in mind that code opinions is to not discover flaws in your programming however it is going to solely make you a greater ABAP developer and keep consistency.
Ensure you write an finish person paperwork with overview of the performance or enhancement upon completion. Embody screenshots the place attainable. Put together documentation maintaining in thoughts that an finish person unfamiliar together with your deliverable can learn the doc and check the performance. Embody contact data on this doc for customers to simply attain the SAP technical crew for any questions.
9. Consumer Acceptance Testing
Now that your ABAP coding is accomplished and reviewed by technical specialists, it’s time for the enterprise customers to carry out a proper person acceptance testing. UAT testers will examine whether or not the output meets enterprise course of necessities and counsel any enhancements or modifications to the delivered performance. After completion of those fixes or modifications it is best to request a proper sign-off on the performance.
10. Migration to SAP Check System and Manufacturing System
High quality assurance engineers will check your performance within the SAP QA setting to confirm that every part is working in your delivered performance as examined throughout person acceptance testing. Additionally any issues in transporting your ABAP objects throughout SAP programs will likely be recognized and addressed throughout this step. If no issues are discovered then your transports will likely be authorised to be migrated to SAP manufacturing system within the subsequent transport cycle.
You have got simply discovered find out how to be an environment friendly SAP ABAP Developer or per say a top quality Senior ABAP skilled proper from writing specs till realizing your implementation in manufacturing system. Use this text as a tenet as there are a lot of extra elements to enhance your self to be ABAP programmer which isn’t attainable to cowl in a quick article like this one. You’ll be able to all the time contact me with any strategies or concepts you might search in your SAP implementation.
