GAEB interface for biddings in german building industry

1. Customer invitation to bid (X83) – GAEB tool

1. Customer creates an invitation to bid and sends GAEB X83.

2. In the GAEB application (e.g. GAEB‑Online, Dangl.AVA, PROMOS GAEB‑XML interface):

   • Page/menu like Tenders / Import GAEB.

   • Action: Import GAEB (*.x83), select the X83 file from your file system.​

3. GAEB tool parses the X83 and presents the BoQ / items list for pricing and calculation.

2. Price and calculate in GAEB tool

1. In the GAEB application, open the imported tender / project:

   • Typical page: Project / Tender Details with an Items List / Bill of Quantities tab.​

2. Estimators maintain:

   • Unit prices, surcharges, discounts, alternates, variants, etc., directly on the BoQ lines.

3. Save the fully calculated bid inside the GAEB tool; this ensures all GAEB rules for X84 creation are satisfied.​

3. Exchange data between GAEB tool and IFS (optional but recommended)

In parallel, integrate BoQ data (not GAEB XML) with IFS:

1. From GAEB tool, export a neutral format (CSV/Excel/JSON/API) containing: items, quantities, prices, structure.​

   • Page: Export / Interfaces / ERP Export.

2. In IFS Cloud:

   • Page: e.g. Sales Quotations / Project Estimating / custom BoQ import page.

   • Action: Import BoQ / Import Lines, map columns to IFS quotation or project structures (item, quantity, description, price).

3. Use Boomi (or other iPaaS) only as the middleware between GAEB tool and IFS:

   • Boomi Process: “GAEB‑BoQ Export → Transform → IFS API”.

   • Boomi handles authentication, field mapping, and scheduling, but not GAEB X83/X84 semantics.​

4. Create and return X84 in GAEB tool

1. Once bid prices are final (either maintained fully in the GAEB tool or synchronized back from IFS):

   • In GAEB application, open the quotation object for that tender.

   • Page/menu: Quotation / Export GAEB or Export GAEB DA84 / X84.​

2. Action: Export GAEB (*.x84) and save the DA84/X84 file, which contains your priced bid according to GAEB rules.

3. Send this X84 file back to the customer via the required channel (portal/email).

5. High‑level integration architecture (who does what)

• GAEB application (e.g. GAEB‑Online, PROMOS GAEB‑XML, specialized construction ERP add‑on):

  • Pages: Tenders/Projects, Items List/BoQ, GAEB Import, GAEB Export.

  • Owns: full GAEB X83/X84 import/export and validation logic.​

• IFS Cloud:

  • Pages: Sales Quotations, Projects, BoQ/Estimation, Customer Orders.

  • Owns: commercial process, costing, project control, reporting.

• Boomi / iPaaS:

  • Processes: BoQ to IFS, Prices from IFS to GAEB tool (if needed).

  • Owns: transport and transformation of neutral data structures, not GAEB formats.

​@TntAnnmaS that means you have done an integration in the past?
