We upgraded a client’s sandbox from R25 to R26. When testing sending over bills via the API, this json no longer works like it did in R25.  We get the following error:

'SuppliedByVendorID' cannot be empty.; SuppliedByVendorID: 'SuppliedByVendorID' cannot be empty.

Here is a screenshot and the json at the bottom.

 

{"Amount":{"value":18200.0},"BranchID":{"value":"EMTS NORTH"},"Date":{"value":"2026-09-29T00:00:00"},"Description":{"value":"BOSS|24193|113977|Mulch for Great Wolf"},"Details":[{"Account":{"value":"5200"},"SubAccount":{"value":"02.00"},"Project":{"value":"X"},"Qty":{"value":1.0},"TransactionDescription":{"value":"Cost of Material -Change"},"UnitCost":{"value":18200.0},"UOM":{"value":"EA"}}],"Hold":{"value":false},"PostPeriod":{"value":"09-2026"},"Project":null,"Status":{"value":"Open"},"Terms":{"value":"N30"},"Type":{"value":"Bill"},"Vendor":{"value":"V0002798"},"VendorRef":{"value":"23496"},"ReferenceNbr":null,"_links":null, "LocationID": {"value": "MAIN"}}

    ​@clayriner   I have checked above payload in the 26 R1 version and I don’t see any issue. In your instance, can you please check after you enter the Vendor, is it populating the Supply Vendor ID in the 
    Financial → Receipt Info ?


    Attached screenshot for reference.

     


     

    Can you please check this, by entering the Vendor in the header section

    We posted two different bills. The first image for the first bill posted successfully with no error returned in the API.  The 2nd bill and 2nd image posted the bill but we still got the error about the SuppliedByVendorID.  

    However, in both images, you can see we do have any field showing the receipt info with the supplied by vendor id that you were referring to in your image.

    1st Bill Succeeded

    2nd Bill Failed
