We are using C# with Swagger definition to access a Web Service Endpoint

We are attempting to perform a filter on the SalesOrderClient GetListAsync and would like to perform a substringof filter on the OrderNbr field to find any orders that contain the value that has been specified.

 

SalesOrderClient soClient = new SalesOrderClient(httpClient);
soClient.BaseUrl = "http://localhost/Acumatica_DEV/entity/Test/20.200.001";

select = "OrderNbr, OrderType, Status, CustomerID, Details/LineNbr, Details/InventoryID, Details/OpenQty";
if (!string.IsNullOrWhiteSpace(e.RequestData.OrderNumber))
    filter = "substringof(OrderNbr.Value, '" + e.RequestData.OrderNumber + "')";
else
    filter = "OrderType eq 'SO' and Status eq 'Open'";

IEnumerable<SalesOrder> salesOrders = await soClient.GetListAsync(select, filter, "details", "", null, null);
foreach (SalesOrder salesOrder in salesOrders)
{
    // Process Results
}

 

When we execute the search the error returned is

Unable to cast object of type 'System.String' to type 'PX.Api.ContractBased.Models.EntitySearchField'.

 

Is there a way to apply the substring, startswith or endswith filters here?

Thanks

Chris

 

Have you tried replacing

‘substringof(OrderNbr.Value,’

with ‘substringof(OrderNbr,’ ?

I tried that first and got the same error.

Substringof function has the reversed order of parameters. 

The first parameter must be constant value and the second parameter must be a field name.

Example

{{sitename}}/entity/Default/21.200.001/JournalTransaction?$filter=contains(BatchNbr,'GL')

So in your case you need:

  filter = $"substringof('{e.RequestData.OrderNumber}', OrderNbr)";

Thank you that fixed it.
