Consider the following client request “Please create a report for us to list expenses”.

Which Oracle EBS tool would you choose? There are plenty of options available:

• Oracle Reports, or
• BI Publisher with PDF or Excel layout, or
• Discoverer, or
• BI Publisher Stand Alone, or
• PDF online generation, or
• Oracle WebADI, or
• Plain SQL*Plus as Concurrent Program, or
• Online review option …

Assuming, you as development lead have to decide, you may decide by available skill set in your development team. However, is this a good decision?

An important question to influence the decision is the “Why” question: why do you need this report, what process is behind, what exactly you like to achieve? We see often data created or printed, although it would be much better to get the data in Excel, and upload changes via WebADI directly.

There are more points that should drive your decision:

• How many of such requirements you have got?
• Has this technique been used in the project already?
• Are there related reusable’s you may gain from?
• How difficult is it to maintain your solution?
• Can you merge this report with another one, to reduce test and maintenance work?

In addition, also your own development standards should guide you a bit to come to a good decision. In one of my own projects, we discussed such topics in our weekly team meeting. By utilizing the team knowledge best, you may come to a better decision, and additionally, your team supports your decision.

Unfortunately, I have rarely seen dedicated team trainings or planned knowledge transfer to support such processes. Often the pressure to deliver on time is too high to have discussion and decision time left. But exactly this can help keeping maintenance costs low by limiting the number of alternative solutions for similar requirements.

Lastly, design decisions should be documented to allow another person taking this over easily. Decisions shall be reviewed and updated regularly, to reflect related procedures or Oracle products respective product versions.

Summary:

Oracle EBS offers plenty of alternatives to implement customizations. Create and maintain a decision tree to support the design process. Do not leave the decision just on developer side. Limit the number of alternative solutions as best as possible; choose one which is the most appropriate also from future maintenance perspective.
