Your client's 20-year-old system has no API. Coasty doesn't need one.
Every S/4HANA program starts by pulling data out of green screens, AS/400s, custom EAMs, and Lotus-Notes-era apps that no connector will ever touch. Coasty drives those legacy UIs the way a person at the keyboard does, so extraction stops being the reason your cutover slips.
The extract is where the timeline dies.
Today the team either writes throwaway screen-scraping scripts against an AS/400 that shifts with every PTF, or a contractor rekeys records by hand into a staging sheet. Both are slow, both introduce errors that only surface during mock load reconciliation, and neither leaves you anything an auditor would accept. When the source system is being decommissioned, there is no second chance to go back and re-pull a field you missed.
How Coasty does it
- 01
Log in and read the screen
Coasty signs into the legacy app with the same credentials a clerk uses, then reads every field on screen by sight. No schema, no API, and no database access required.
- 02
Extract the full set, not a sample
It pages through the complete master and transaction data (customers, materials, equipment, open items) and writes each field to a structured file mapped to your S/4HANA load template.
- 03
Reconcile against the target load
Every extracted value is checked field by field against what lands in S/4HANA after mock load, with a screenshot of the source screen attached to each record.
