Short answer

abas ERP and proALPHA are typically run on a company's own servers in the DACH region, so a private AI layer fits: read through each product's documented interfaces or a database reporting copy, index documents locally, and serve a German-capable open-weight model on your own GPU. Data does not need to leave your premises.

Applies to: abas ERP and proALPHA releases run on your own infrastructure. Interface options differ by release and licence; confirm with your vendor or partner.

Reference build for a private AI layer on abas or proALPHA

  1. 1Identify the product and release, and the interface your licence includes. For abas this means the vendor's documented programming interfaces rather than a standard SQL database; for proALPHA this includes its database and documented integration options.
  2. 2Create a reporting layer: for proALPHA a read-only database copy and curated views; for abas a scheduled export or an interface-based reader that writes to a reporting store.
  3. 3Define approved entities: articles, customers, vendors, sales and purchase orders, production orders, stock and invoices. Exclude personnel and payroll.
  4. 4Create a service identity with read-only rights and no administrative functions in the ERP.
  5. 5Index documents tied to records: drawings, order confirmations, certificates, contracts and work instructions, in German and English, with the ERP number as metadata.
  6. 6Expose a few parameterised read tools through an MCP or REST tool server, so the model never builds free queries against the ERP.
  7. 7Serve an open-weight model that handles German well using vLLM or Ollama on local GPUs, and block outbound traffic.
  8. 8Log every question, tool call and result, and agree the retention period with your data protection officer.

How the two systems expose data

abas ERP stores data in its own database and is accessed through the vendor's interfaces, such as the EDP interface and Java-based object access, with newer releases adding web-style APIs. Because it is not a plain SQL database, the practical pattern is an interface-based reader that exports approved records into a reporting store, or a vendor-supported reporting option.

proALPHA has historically run on the Progress OpenEdge database, which supports SQL over JDBC or ODBC, so a read-only copy with curated views is feasible; releases and licences determine exactly what is available. Table and field names follow the product's data dictionary, which you should consult rather than guess.

In both cases, use documented interfaces for any writing. Direct updates risk breaking consistency that the application enforces.

Reference architecture, GDPR and air-gapped use

The layers are a reporting store, curated views or exports, a refresh job, a vector index, a tool server, a model server and an audit log, all inside your network. For many DACH manufacturers the point is data residency and control: processing stays at your site, under your own technical and organisational measures.

Choose a model that handles German technical language well. Several open-weight families do, and a short evaluation on your own order texts and part descriptions is worthwhile before you commit to one.

For air-gapped plants, weights and packages arrive on controlled media and the enclave has no route out.

Permissions and write-back

Both products have their own user, role and organisation concepts. The tool layer maps each person to those roles and filters tool calls, and document chunks carry labels from their source folder or record. Cost, margin and personnel fields default to deny.

Works council and data protection requirements often apply to systems that process employee-related information. Keep personnel and time-recording data out of scope unless the works council has agreed.

Write-back, when added, goes only through documented interfaces and creates drafts that a named person approves.

Sizing, rollout and limits

Typical sites have a few hundred named users with a minority active each day, which fits one or two GPUs. Time goes into the reporting layer and into evaluating German-language quality.

Phase 1 is read-only questions on orders, stock and production. Phase 2 adds drafts such as supplier reminders. Phase 3 adds approved actions via documented interfaces.

Limits: abas needs an interface-based export rather than direct SQL, customisations require mapping, and vendor-provided analytics or AI may already cover simple needs. Check what your release offers before building.

Common pitfalls

  • !Assuming abas is a plain SQL database and designing around direct queries.
  • !Guessing proALPHA table names instead of using the data dictionary.
  • !Skipping a data protection and works council review before indexing employee-related data.
  • !Choosing a model without testing German technical vocabulary.
  • !Giving the service identity administrative ERP functions.
  • !Writing back through anything other than documented interfaces.

How an ERP-grounded AI assistant handles this

ERPray can answer German or English questions such as which production orders are blocked by missing material, by calling approved views and showing the source. Netray builds the local model serving, retrieval index and tool server, and your abas or proALPHA partner remains the authority on your configuration.

Frequently asked questions

Can we use AI with abas ERP on-premise?

Yes. Use abas's documented interfaces to feed a reporting store, index documents locally and run an open-weight model on your own GPU. Details depend on your release and licence, so confirm the interface options with your abas partner.

Does proALPHA work with a local LLM?

Yes. A read-only copy of the proALPHA database with curated views, plus a local retrieval index and model, keeps data on site. Use the data dictionary for table meaning and the documented routes for any writing.

Is this GDPR friendly?

Keeping processing on your servers removes the third-country transfer question, but you still need a lawful basis, access controls and logging. Involve your data protection officer and, where applicable, the works council.

Will it understand German?

Several open-weight models handle German well. Test candidates on your own part descriptions, order texts and abbreviations before choosing, because ERP language is more terse than general text.

How to Add AI to Macola ERP On-Prem Without Sending Data to a Cloud

Macola 10 runs on SQL Server, so the safest pattern is a read-only reporting copy of the Macola company database, a small set of approved views, a retrieval index over attached documents, and an open-weight model served on a local GPU. Writes stay out of the first phases and, when added, go through Macola's supported import or SDK routes with a person approving each one.

Self-Hosted Odoo AI Assistant: Private Architecture With a Local Model

Self-hosted Odoo already exposes its data through an authenticated external API that enforces access rights and record rules, so a private assistant can call it as the signed-in user. Add a retrieval index over attachments and a local open-weight model, and nothing leaves your servers. Direct PostgreSQL access is for aggregates only, because it bypasses record rules.

Odoo raises AccessError when a user's security groups do not grant a CRUD right on a model through ir.model.access.csv, or when an ir.rule record rule filters the specific record out for that user or company. Fix it by adding the user to the group named in the error, editing the model's access rights, or reviewing the record rule's domain under Settings > Technical > Security.
