README

An Erpy connector for SAP Business One.

Free. Erpy itself is the paid part — it owns the sync engine, the identity map, the field mapping, the queue, the dead letters and the log. This package's whole job is to translate one vendor's API into Erpy's canonical documents.

Installing

composer require justinholtweb/craft-erpy-sapb1
php craft plugin/install erpy-sapb1

Then add a connection under Erpy → Connections and pick it from the ERP list.

What you need to know

Authentication

A Service Layer session, established once and closed explicitly. B1 licences are consumed per session and leak if you never log out.

Delta syncing is day-granular

B1 keeps UpdateDate and UpdateTime in separate columns and only the date is filterable, so a delta sync reads everything changed on or after the watermark’s date. Erpy’s change detection makes the re-read cheap.

Booleans are strings

B1 answers tYES and tNO. (bool)'tNO' is true, which is how integrations end up publishing every frozen item — handled here.

What it syncs

The connection screen shows exactly which entities and directions this connector supports — it is generated from the connector's own declaration, so it can never advertise a flow it has not implemented.

A field is wrong

Correct it on the mapping screen: a rule whose target is a canonical field (sku, unitPrice, customerCode) overrides what the connector read, before anything reaches Commerce. No fork, no wait for a release.

Requirements

Craft CMS 5.3+, Craft Commerce 5.0+, PHP 8.2+, and Erpy 5.0+.
