My AS400 users keep hitting application-specific error messages whenever they work in the Inventory Management module. We are not seeing any login problems or general performance slow-downs—just these disruptive messages tied directly to inventory functions. I need someone who really knows the AS400 stack (RPG, CL, DB2) to: • Reproduce the Inventory Management errors, identify the root cause in code, configuration, or data • Implement and test a clean fix in our DEV environment, then migrate it safely to PROD • Document the change and the steps we’ll need to follow for future maintenance Acceptance criteria: no error messages during standard inventory workflows (add, update, inquiry, and report generation) for at least one business day after deployment, with all regression tests passing. If you have recent hands-on experience troubleshooting AS400 applications, I’d like to get this resolved quickly.

Hi there, I will trace the Inventory Management error messages through the RPG and CL source, pinpoint whether the root cause sits in code logic, DB2 data integrity, or module configuration, then deploy a tested fix from DEV to PROD with full documentation. On a similar AS400 inventory fix, isolating the failing SQL call in the update routine resolved the issue without touching surrounding modules. Questions: 1) Are the errors triggered by specific workflows (add, inquiry, reports) or all of them? 2) Do I get direct access to the DEV partition and job logs? Share a screenshot of the error messages and I will start diagnosis today. Looking forward to your response. Best regards, Kamran

Greetings, I see that you're facing issues with error messages in the Inventory Management module of your AS400 system. It sounds frustrating, especially since there are no login or performance issues. My approach would be to first replicate the error messages to understand the specific triggers. I would dive into the RPG and CL code, along with the DB2 database configurations, to pinpoint the root causes. Once identified, I’ll implement a fix in your DEV environment and conduct thorough testing to ensure all inventory workflows run smoothly. I’ll also document the changes and provide guidelines for future reference, ensuring your team can maintain the system effectively. With my hands-on experience in troubleshooting AS400 applications, I’m confident we can resolve this issue quickly. Best regards, Saba Ehsan

I can help with this, We will trace the inventory module errors to their source in the RPG/CL code and DB2 data, fix them in DEV, and migrate a tested change to PROD with full documentation. Our first step will be reviewing the job logs and message queues tied to the inventory programs. Most module-specific errors like these point to a data condition the code does not handle (decimal data errors, record locks, or missing file members). A couple of quick things to confirm: 1) Do you have the error message IDs or job log output available? 2) Is your DEV environment a mirror of PROD, or a separate LPAR? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Send me a message and we can go over the details.

Inventory module error messages on AS400 can be caused by RPG/CL logic, DB2 constraints, wrong environment/config, or corrupted inventory data paths. I’ll reproduce the errors in DEV by running the same add/update/inquiry/report workflows your users trigger, capture job logs, message IDs, and failing program points, then isolate the root cause in the relevant RPG/CL components and any DB2 queries/overrides. Once identified, I’ll implement a minimal, safe fix with targeted unit/regression coverage across standard inventory workflows (add, update, inquiry, report generation). I’ll validate with representative DEV data, then deploy to PROD using a controlled migration approach and a rollback plan. After go-live, I’ll monitor to confirm zero disruptive messages for at least one business day and that regression tests remain fully passing. I’ll also document the exact change, affected objects, dependencies, and the maintenance steps/troubleshooting checklist so your team can verify behavior quickly in future releases.
