The challenge: 16 months of AnaCredit reporting to resubmit
AnaCredit (Analytical Credit Datasets) is the European Central Bank's granular reporting framework, which requires credit institutions to have a detailed view of their loan portfolio. In the event of a quality gap identified in the historical reports, the regulator requires the complete resubmission of the reports concerned — a cumbersome technical exercise, subject to short deadlines.
For our client, the challenge was structural: 16 months of reporting to be reproduced, on 3 legal entities, across 4 data domains — Instruments, Counterparty Repository, Counterparty Risk, Protections — for a total of more than 22 million data points to be validated.
The existing production chain was based on a manual assembly of tools (Excel, Java enrichment scripts, manual corrections), without end-to-end traceability. The initial budget estimated the remediation effort at 800 man-days.

Our conviction: an industrial chain, not a manual sprint
Large-scale regulatory reporting cannot be solved by the occasional strengthening of teams. Prime Analytics proposed an industrial approach: replacing the fragmented chain with a single Alteryx workflow, integrating the entire cycle — pre-processing, quality controls, automated corrections, generation of regulatory XML in accordance with BCE schemas.
Four principles guided the design:
1. Integrated quality controls
Integrated into the workflow, and not applied afterwards.
2. Automated corrections
On recurring error patterns, without human intervention.
3. End-to-end traceability
Every step, from the source file to the final XML, is auditable.
4. Reusability
A pipeline for all entities and all reporting periods.
Before/After
The contrast between the historical chain and the industrialized chain illustrates the extent of the transformation, carried out in less than 10 weeks.
• Production time: went from 6 man-days to 1 hour by report and by entity — a production ratio divided by 50.
• Tools: replaced from a fragmented Excel/Java string by a unique Alteryx workflow, end-to-end and repeatable.
• Corrections: went from manuals to automated on all recurring error patterns.
• Traceability: changed from limited coverage to complete traceability, from the source file to the XML sent to the ECB.
• Knowledge: went from focusing on a few experts to an autonomous and trained reporting team.
— A long-term transformation: the customer now operates this chain independently for its recurring AnaCredit cycles.

Framing, automation, training: an end-to-end partnership.
16 months resubmitted within the BCE deadline
In less than 10 weeks, the complete scope was produced, checked and sent to the regulator. In addition to immediate performance, the client now has an industrialized chain that it operates independently for its recurring AnaCredit cycles — and that it is now extending to other regulatory reports.
We were waiting for a remedy. We got an industrial production line. It is the best way to respond to a regulator. “With Prime Analytics, we were able to get this project up and running in just a few days. Their knowledge of Alteryx and their technical expertise allowed us to move quickly and obtain greater precision than we expected. This model has made us gain in reliability, speed and autonomy.”

Key takeaways of the project
100 man-days delivered compared to 800 initially budgeted (− 87%)
22 million+ data points validated on 3 legal entities
93% of errors automatically corrected by the workflow thanks to the expertise of Prime Analytics
16 months of reporting resubmitted within the ECB deadline
A reusable chain now operated independently by the customer business teams on Alteryx and data management
