Fix AS400 Custom Feature Bug

@techplusintl

Hi, To restore the functionality of your in-house AS400 application, I will dive into the source code using RPG, CL, or any relevant language to identify the root cause of the malfunction. I will utilize the provided source members and sample data to trace the fault effectively. Once I pinpoint the issue, I will modify or rewrite the necessary programs and service programs, ensuring to re-compile and test the changes thoroughly. I will also provide annotated code changes along with a hand-over note for your internal team’s future reference. I am familiar with tools like RDi and can work with remote VS Code if needed. I understand the importance of a quick turnaround and will prioritize delivering a tested patch as soon as I gain system access. Happy to discuss the details.

@koolvishruth

Hello Sir, I have 7 years of experience in backend debugging, legacy system support, database-driven applications, and production issue resolution. I will review your AS400/iSeries application source, trace the broken feature, identify the root cause, and provide a clean tested fix in the test LPAR before anything moves to production. I will examine the RPG/CL source members, object dependencies, files, triggers, calculations, and sample failure data. After the fix, I will recompile, test the corrected output, and provide annotated code changes with a short handover note for your internal team. Once I receive access, source details, and sample data, I can give an exact turnaround estimate. For isolated feature bugs, I usually expect 1–2 days depending on complexity. Regards, Vishruth

Hello. This is Bravion from Cleveland. My method to complete this project involves first accessing your test LPAR environment to safely analyze the source code using RDi or a preferred IBM i IDE. I will trace the bug by reviewing the RPG and CL code logic, isolating the root cause through debugging and test data you provide. Then, I will implement a clean fix, recompile, and thoroughly test the feature to ensure accurate calculations and outputs, followed by delivering annotated code and a concise hand-over note. Could you please confirm which IDE you prefer me to use and your expected turnaround time after I gain access? Also, is there any existing documentation on recent changes to this feature? If you want high-quality results, please do not hesitate to contact me.

I’m ready to jump straight into the AS400 iSeries custom feature and restore the broken functionality. Approach: I’ll use your provided source members, object names, and functional spec to trace the failure path in the relevant RPG/CL (or other library code you confirm). With the reproducible sample data and your test LPAR access via Client Access/ACS, I’ll compile/debug safely, pinpoint the root cause, and implement a clean fix (member/service program/file/trigger as needed). Deliverables: recompiled code with the correct behavior verified on the test environment, plus annotated code changes and a concise hand-over note your internal team can maintain. I can also describe the exact tooling (RDi/PDM/SEU/remote VS Code with Code for IBM i) so you can enable required ports. Timeline: once access is granted and I can reproduce consistently, I’ll provide a tested patch with a delivery estimate based on the scope of the impacted members and the time required to validate with your sample dataset.

@ziedb4

Hi, I can take this on — comfortable jumping into RPG (free/fixed) and CL source without prior context, which is what this needs. Approach: Review source members, object names, and your functional spec to scope the fault Use the sample data that reproduces the failure to trace it directly — reliable repro is the fastest path to root cause here Isolate whether the issue is in program logic, a service program interface, file definitions, or a trigger Modify/rewrite the affected code, recompile on your test LPAR (won't touch production) Re-test against your sample data until the feature produces correct calculations/outputs Deliver annotated code changes plus a short hand-over note so your internal team can maintain it going forward I'm comfortable with RDi, PDM/SEU, or VS Code with Code for IBM i — whichever you prefer, just let me know so the right ports/access get enabled. If it's VS Code + Code for IBM i, I'll need SSH/DB2 connection details in addition to Client Access/ACS.
