The Context-First Method: How to Cut ERP Reporting Migration Time by 70%
No new headcount. No consultant.
Every ERP transformation eventually hits the same wall. The go-live plan has a line item for data migration. For system integration testing. For training. What it almost never has is a line item for reporting continuity.
And then month three hits. Finance can't close. Sales can't see pipeline. Operations is running on Excel exports from a system you're trying to retire. And your BI team is staring at a backlog of broken dashboards with no clear path through.
This is not a technology problem. It is a context problem.
Here is the method we use to solve it — and how we cut reporting migration time by 70% without adding headcount or bringing in a consultant.
The setup: two buckets, one starting point
When an ERP transformation impacts your existing Tableau dashboards, every affected workbook falls into one of two buckets.
In both cases, the starting point is identical: the backend SQL query powering the Tableau data extract. And in both cases, the bottleneck is identical: before anyone can write a single line of SQL, they need to understand the old data model, the new Fusion structure, the field mappings between them, and the business logic the dashboard was built to serve.
That context-gathering process — done manually — is what was eating three-plus weeks per workbook.
We stopped doing it manually.
The context-first method
The insight is simple: the reason AI-assisted SQL generation produces garbage output for most teams is not that the AI is bad. It is that the context going in is thin.
The teams getting real results are doing something different. They are building a rich context package before they write a single prompt. Then they use that context to generate a precise, 1-shot prompt for SQL generation — not a vague instruction, but a fully loaded specification.
The method has four phases. Phase 1 alone eliminates 70% of the previous time-to-delivery...
