UPDATE Handling Unit using API_HANDLINGUNIT does not work.

[tony_raimo2]

I'm trying to call the public API to update a Handling Unit in an S/4 2023 on-prem system.  The GET operation works, however, the PATCH operation throws this error.  Has anyone seen this error before?

{

    "error": {

        "code": "HU_RAP/066",

        "message": "Operation UPDATE not supported for LO-HU",

        "@SAP__common.ExceptionCategory": "Provider_Application_Error",

        "innererror": {

            "ErrorDetails": {

                "@SAP__common.Application": {

                    "ComponentId": "LO-HU-API",

                    "ServiceRepository": "SRVD_A2X",

                    "ServiceId": "API_HANDLINGUNIT",

                    "ServiceVersion": "0001"

                },

                "@SAP__common.TransactionId": "8452C63109A70020E0066FDA3E13200B",

                "@SAP__common.Timestamp": "20241114013306.193137",

                "@SAP__common.ErrorResolution": {

                    "Analysis": "Use ADT feed reader \"SAP Gateway Error Log\" or run transaction /IWFND/ERROR_LOG on SAP Gateway hub system and search for entries with the timestamp above for more details",

                    "Note": "See SAP Note 1797736 for error analysis (https://service.sap.com/sap/support/notes/1797736)"

                }

            }

        }

    }

}

Here are some more details about how I'm making the call in PostMan:

Thank you,

Seems like you can't UPDATE a handling unit.

API Hub says you can "Create, read, delete and post goods movement ..." does not mention update.

Dude - where's my API? 

[tony_raimo2]

The API documentation shows PATCH as a valid operation to update an HU. https://api.sap.com/api/HANDLINGUNIT_0001/resource/

Hi Tony,

please be aware that the HU API was developed for the public cloud and is only enabled to work in on-prem / private cloud environment when you implement BAdI /SCWM/EX_API_CTRL_USE to suppress this error message. Only then you can use the patch call to update weights and dimensions of an existing HU in the on-prem System.

For more info check SNOTE 3216941.
