[REST API] - Purchase Order Action - Open/Hold

Hello Developers,

I hope everything is going well.

I'm currently working on implementing a feature to "Hold" a Purchase Order using the Rest API. I've set up the necessary actions in our web services.

Here's the rundown:

1. Actions - WebServices

2. This is the Purchase Order I'm attempting to put on "HOLD."

2- 

This is Purchase Order I”m trying to “HOLD”

 

I've sent the request using the following endpoint: https://company.acumatica.com/entity/vendorpolineitems/22.200.001/PurchaseOrder/Hold

4- Request Body 

 

{
    "entity": {
        "Type": {
            "value": "Normal"
        },
        "OrderNbr": {
            "value": "PPO05340"
        }
    }
}

Unfortunately, I encountered the following error:

"source": "application", "code": 500, "message": "{\"message\":\"An error has occurred.\",\"exceptionMessage\":\"Operation failed\",\"exceptionType\":\"PX.Data.PXInvalidOperationException\",\"stackTrace\":\" at PX.Api.ContractBased.EntityService.Invoke(ISystemContract systemContract, String version, String name, EntityImpl entity, ActionImpl action, CbOperationContext operationContext, Boolean throwOnError)\\r\\n at PX.Api.ContractBased.Soap.SoapFacadeBase.InvokeImpl(EntityImpl entity, ActionImpl action, Boolean throwOnError)\\r\\n at PX.Api.ContractBased.SystemContracts.V4.Facade.PX.Api.ContractBased.IRestGate.Invoke(EntityImpl entity, ActionImpl action, String objectName,

Thanks
