Profitable & Resourceful SAP ABAP Developer
ABAP / ABAP OO improvement are very essential in addressing any resolution gaps, RICEFs or customized improvement on any SAP challenge. I believe it is vitally essential to know numerous 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 Crew Lead
1. Assessment Enterprise Necessities & Write Purposeful Specification
The primary a part of any ABAP improvement challenge start with assembly the tip customers or enterprise consultants and perceive the enterprise necessities that must be carried out within the SAP system in the course of the realization section. A greatest method is to conduct workshops to assemble all of the enterprise necessities. Be sure that 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 practical marketing consultant or enterprise professional will write an in depth practical specification. Assessment the practical specification till the doc has all the main points, totally different enterprise situations and anticipated targets clearly outlined. A effectively outlined practical specification ought to comprise UML diagrams and take a look at case situations. It is very important have an official signoff on the practical specification earlier than persevering with with design and improvement.
2. Assessment ABAP Growth Requirements
In best case, your SAP Challenge Lead or ABAP Growth Supervisor ought to have created a programming requirements and pointers doc. Assessment this doc so that you just comply with the naming conventions for operate modules, lessons, dictionary objects, software program parts, title areas and proxies (if utilizing SAP XI / PI), program enter/output parameters, and so forth simply to call a couple of. Following the rule of thumb for the challenge helps preserve a constant coding method and likewise helps different practical and technical analysts to learn and debug your code. ABAP objects naming ought to start with Z if will probably be migrated to SAP manufacturing system and Y if it won’t be migrated into the manufacturing system.
three. Write and Assessment Check Instances
The take a look at case paperwork are written by the enterprise consultants or practical SAP consultants in most SAP implementation initiatives. However on some SAP implementation initiatives a programmer could also be required to write down take a look at instances. Earlier than writing a take a look at case assessment the practical specification doc totally and assessment the written take a look at case with the enterprise customers or practical 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 aim has been to maintain my staff motivated and all the time cowl the staff 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 staff and challenge administration staff preserve in sync which is a crucial to finish the SAP implementation in time and finances.
four. Write and Assessment Technical Design Specs
Learn the practical specification and listing all the event objects that might be wanted to implement the required performance within the SAP system. First step is to attract a flowchart and assessment with technical and enterprise consultants. The technical design doc ought to embody a technical overview, listing of latest database objects, ABAP objects that may be reused, a knowledge mannequin and sophistication diagram (if utilizing ABAP OO lessons). It’s extremely really helpful to have a tough prototype within the sandbox system (Growth system if no SAP sandbox system is on the market) if the event being completed is complicated or if the tip deliverable is just not effectively outlined. You need to then assessment your prototype with practical consultants and enterprise customers. Be sure that the ABAP Growth staff lead or supervisor indicators off on the prototype. If effort required to finish the ABAP programming job is just not offered and authorised by the senior challenge administration then this might be time to get the event estimate and timeline authorised.
5. Realization of the Specification – ABAP Growth
Throughout this step you’ll be creating improvement objects and implementing the code within the SAP improvement system. Earlier than you start, if prototype was completed 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 essential than strictly following the design specification. Decide which present dictionary objects will be reused for this matter. If new dictionary objects or lessons must be created then make sure that these objects will be prolonged and reused for different improvement duties. It might require further effort to develop objects which are reusable and versatile. This one time effort for constructing reusable ABAP objects in the course of the course of a improvement challenge can probably save numerous work for programming comparable objects that might in any other case make the most of already constructed objects. Assessment your method with an SAP technical staff lead or a improvement supervisor in your challenge earlier than deviating from the technical design specification and implementing your personal concepts. In case you are concerned in SAP XI (now Course of Integration) associated duties or creating enterprise companies then that is the perfect space the place you might reuse present objects. Assessment the message varieties that exist already inside your SAP enterprise unit and see if any present messages will be prolonged with new fields. Assessment with the staff lead whether or not the communication needs to be synchronous or asynchronous earlier than you generate proxies.
6. SAP Growth Finest Practices
SAP ABAP (or JAVA if engaged on SAP Netweaver) improvement greatest practices needs to 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 staff on all initiatives and it has been an incredible success in delivering top quality output on all improvement duties. Listed here are a couple of greatest practices price adapting in your challenge. Examine whether or not you adhere to all naming conventions as described within the programming requirements set in your implementation challenge. Embrace feedback in your code to permit another person to simply perceive your packages. That is significantly useful once you work in massive groups and a number of individuals work with identical objects. Guarantee that you’ve test for person authorization in case you are constructing transactions or net user-interfaces that may require human interplay. Examine that you just should not 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 options could also be possibility), and so forth. Subject symbols are an ideal asset in the case of processing inner tables and likewise variables with unknown information varieties which are resolved at runtime. Subject symbols are similar to idea of utilizing pointers in OO programming panorama. Examine if all exceptions are dealt with and error messages are communicated precisely to the tip customers. As an ABAP programmer it needs to be effectively accepted by now that quick dumps shouldn’t be OK to happen. All these do happen in unknown particular case situations the quick dumps needs to be fastened.
7. ABAP Code Opinions and Efficiency
As a ABAP programmer you need to take a look at your code upon completion for all doable situations. Confirm that finish outcomes are identical as that anticipated within the documented take a look at instances. Carry out ABAP runtime evaluation to test for efficiency of your code. Search options out of your technical staff lead or supervisor on the best way to enhance code efficiency should you discover any pink flags in the course of the runtime evaluation. Schedule a proper code assessment 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 take a look at scripts. Keep in mind that code critiques is to not discover flaws in your programming however it can solely make you a greater ABAP developer and preserve consistency.
Be sure to write an finish person paperwork with overview of the performance or enhancement upon completion. Embrace screenshots the place doable. Put together documentation maintaining in thoughts that an finish person unfamiliar together with your deliverable can learn the doc and take a look at the performance. Embrace contact info on this doc for customers to simply attain the SAP technical staff for any questions.
9. Person Acceptance Testing
Now that your ABAP coding is accomplished and reviewed by technical consultants, it’s time for the enterprise customers to carry out a proper person acceptance testing. UAT testers will test 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 you need to request a proper sign-off on the performance.
10. Migration to SAP Check System and Manufacturing System
High quality assurance engineers will take a look at your performance within the SAP QA setting to confirm that all the things is working in your delivered performance as examined throughout person acceptance testing. Additionally any issues in transporting your ABAP objects throughout SAP methods might be recognized and addressed throughout this step. If no issues are discovered then your transports might be authorised to be migrated to SAP manufacturing system within the subsequent transport cycle.
You’ve got simply discovered the best way to be an environment friendly SAP ABAP Developer or per say a top quality Senior ABAP professional proper from writing specs till realizing your implementation in manufacturing system. Use this text as a suggestion as there are numerous extra elements to enhance your self to be ABAP programmer which isn’t doable to cowl in a short article like this one. You’ll be able to all the time contact me with any options or concepts you could search in your SAP implementation.
