ERP Reporting Query Quality Assessment
ERP reporting problems rarely come from SQL syntax. They come from where queries run, who can change them and whether anyone checks the numbers. This assessment scores those habits in ten questions.
1. Where do your SQL reports and ad hoc queries run?
Running heavy queries on the live transactional tables is the main source of ERP slowdowns.
2. What database access do report writers have?
3. How are queries stored?
4. How do you validate a new report before people rely on it?
5. How well documented are the table joins and business rules in your reports?
6. How do you handle query performance?
7. Do your reports use SELECT star, NOLOCK hints or functions on filtered columns?
8. What happens when the ERP is upgraded or a table changes?
9. How is sensitive data such as pay rates, prices or controlled technical data handled in reports?
10. Who owns each business report?
How to use the assessment
Answer each question for the way your team actually works today, not how you intend to work. Pick the option that describes the typical case. If practices vary between departments, answer for the busiest reporting team or run it once per team. The score is shown as a percentage of the maximum and mapped to a band with specific next steps. Use it to start a conversation with IT, finance and operations about what to fix first.
What the questions measure
Questions one and two look at blast radius: where queries run and who can change data. Questions three to five measure repeatability: storage, validation and documentation. Questions six and seven look at performance habits that affect everyone on the ERP. Questions eight to ten cover upgrade resilience, sensitive data and ownership. A low score in the first two areas is more urgent than the rest, because they can cause outages or data damage.
Turning the score into action
Pick the two lowest scoring answers and set a 30 day goal for each, for example moving the five heaviest reports to a replica, or reconciling the finance reports to the ledger. Avoid trying to lift all ten at once. Repeat the assessment after each ERP upgrade and when a reporting person leaves, since those are the moments when undocumented knowledge disappears.
Common mistakes
Teams overrate documentation and testing because they happen informally. If only the author can explain a report, it is not documented. Another common mistake is treating read-only access as harmless: a careless report can still lock tables or expose pay data. Finally, do not equate a fast report with a correct one, since a quick query with a wrong join returns wrong numbers very efficiently.
Frequently Asked Questions
Does this assessment apply to every ERP?
Yes. The questions are about practice rather than product. It applies whether you use SQL Server, Oracle or another database under SAP, Infor, Epicor, Dynamics, NetSuite exports or a custom ERP.
What is a reporting replica?
A read-only copy of the ERP database, kept current by replication, log shipping or availability group, so heavy queries do not compete with transactions. Latency of seconds to minutes is common.
Why avoid SELECT star in reports?
It reads columns you do not need, breaks when the ERP adds or reorders columns, and can expose sensitive fields. Listing columns explicitly makes reports clearer and more stable across upgrades.
How often should I retake it?
Annually, plus after each ERP upgrade, major reporting staff change or move to a new reporting platform. Compare the answers to see which practices improved.
If your reports need a governed, read-only layer on top of the ERP, we can help design it and show what it would take.
