Posted on by CU17041118-0

Hello,

I'm working on a intercompany process where company A creates a purchase order, and then sends the IC document and generates a sales order in Company B,

I want when i validate the sales order in Company B for shipment, it automatically post the purchase order of Company A for receiving

I tried with changecompany + using standard purch-post codeunit it didn't work

I tried also with session.startsession and it didn't work too

Does anyone have any suggestion ?

Thanks in advance

I'd use IC Outbox/Inbox + IC Transaction Posting Flow instead of direct posting

I believe you problem related to :

You can send sales and purchase orders and return orders before posting. Invoices and credit memos can't be sent until they're posted.

Hello,
in BC SaaS I would not recommend posting Company A’s purchase order directly from Company B’s sales order posting using ChangeCompany or StartSession; even if you can read/change records across companies, the standard posting routines are not designed to safely post another company’s document inside the same transaction/context, and you can easily hit locking, permissions, commit, posting preview, number series, or inconsistent IC audit issues. The cleaner approach is to keep the IC process standard: post the shipment in Company B, send/accept the IC document/message, then post the receipt in Company A either manually, via Job Queue / background process in Company A, or via an integration/API call that runs in Company A’s company context. If you need full automation, create a custom queue table/event when Company B shipment is posted, then have a job queue in Company A pick it up and run the purchase receipt posting there; that keeps each company posting its own document and avoids cross-company posting problems.

This is likely a limitation of the ChangeCompany method. I suggest you use a Job Queue for posting, although it's not real-time, it should solve the problem.

Thanks.

Hello,

You can’t reliably auto-post a Purchase Order in another company using Change Company or Session Start Session, as standard posting code units require a proper session and company context; instead, you should decouple the process: when the Sales Shipment is posted in Company B (via event subscriber), identify the related IC Purchase Order in Company A and trigger its receipt posting asynchronously using a safer approach such as a web service/API call, a Job Queue entry, or a custom queue table processed within Company A—this aligns with Business Central best practices, avoids cross-company transaction issues, and ensures stability and consistency.
