Bapi_Salesorder_Createfromdat2: not set an instance

[Former Member]

Hello all,

I have a problem when I use the BAPI function :

Bapi_Salesorder_Createfromdat2

I code in C# in MS Visual Studio .Net 2003

In my code, I create all connector passed by argument in the BAPI function :

Ex :

protected PortalDevelopment.ConnecteurSAP.BAPISDHD1 OrderHeaderIn ;

...

OrderHeaderIn = new PortalDevelopment.ConnecteurSAP.BAPISDHD1() ;

...

I affecte :

OrderHeaderIn.Doc_Type = TextboxTypeCmdeClient.Text ;

OrderHeaderIn.Sales_Org = TextBoxOrgCom.Text ;

OrderHeaderIn.Distr_Chan = TextBoxCanalDistrib.Text ;

OrderHeaderIn.Division = TextboxSecteurActivite.Text ;

OrderHeaderIn.Purch_Date = "08.11.2005" ;

OrderHeaderIn.Purch_No_C = TextboxNumCmde.Text ;

NumCustomer.Partn_Numb = TextBoxDonneurOrdre.Text ;

NumCustomer.Partn_Role = "WE" ;

OrderPartners.Add(NumCustomer) ;

NumCustomer.Partn_Numb = TextBoxReceptionnaire.Text ;

OrderPartners.Add(NumCustomer) ;

ItemOrder.Material = "M-01" ;

OrderItemsIn.Add(ItemOrder) ;

OrderSchedulesIn0.Req_Qty = "1" ;

OrderSchedulesIn.Add(OrderSchedulesIn0) ;

But when I call Bapi_Salesorder_Createfromdat2 with all arguments, I receive a error message :

Object reference not set to an instance of an object.

I have forgot to create a "new" or I have forgot a obligatory attribut?

Everyone can help me?

thank you

I agree. Always test the function from SE37 prior to trying to invoke remotely.

Also, some of the data types passed to the call need to be initialized before the call. Specifically, look for types passed by ref and initialize them prior to the call.

ZBALANCEDETAILTable detailTable = new ZBALANCEDETAILTable();
					
proxy.Z_Rfc_Ar_Acc_Aging(companyCode, account, "X", "", "", "0000", rfcKeyDate, ref <b>detailTable</b>);

Thanks,

Eric Cadwell,

Thank you for your answer.

I have try the function from the single test from SE37 and the order was created.

In my code, I have created and initialized the type passed by reference and I have put the same value that my test.

Thanks,

That should have taken care of the null pointer error. Is it still not saving?

We had problems with dates not being sent it correctly. Certain dates required by the call must be initialized to "00000000" or set to a valid date.

Search google groups for an example:

Hi Eric,

I have look the google groups and I have put the date at the good format. I have put values at all attibuts like example which to be in google groups.

For the "not set to an instance", I have put the creating connector in the same methods that creating order, just to test.

I think that I have not put value in all obligatory attributs in argument passed by reference but I don't know which. Are you one idea?

Thanks

Can you create a simple order as the example shows? This exmaple doesn't include partners, items, or schedule lines, just the required header data. Start simple and work up to the more complex scenario.

If you're getting "object reference not set to an instance" you should be able to break in debugger and see what's null.

Hello Eric,

I have testing a simple order without partner, items and schedules lines like in the example. But I have always the error.

I have launched the application in debugger mode and the error occurs when the function BAPI_SALESORDER_CREATEFROMDAT2 is launched. But I have not details where is exactly the error. All values that I have fill is good in the debugger mode and others are null. Can I fill all values?

But I see that the function in the example is not same that mine. In the example, the function is BeginBapi_Salesorder_Createfromdat2 and the argument is not in same place.

Is possible that the error is in my SAP version?

Thanks

If I look at your code I can nowhere find a place where you assign a Connection to your proxy or create the connection implicitly using a connection string or Destination. Could this be the problem? (proxies without a connection may throw exceptions...).

Hello Reiner,

Thank you for your answer.

I have forgot to assign a connection... Now the problem of .Net error is resolved.

Thank you very much

I don't think I can give you a specific response, but I can give you some hints.

1) Write a simple ABAP program and attempt to run the FM in SAP with the data you are sending it in your program. Most of the time if it fails when you call it externally, it will fail when you call it internally.

2) Sometimes when you send a sales order number or a delivery or things like that - if you do not pad the zeros when you call up to SAP, it will fail with 'something doesn't exist'.

3) The error you are getting is a typical VS.NET error. This could be coming from a couple of places. When you declared your proxy variable - you did not declare it as new. You are using a separate sapConnection variable and it was not set to new when you set it to the connection property of the proxy. Any of the table type parameters going to the function module are not declared as new when they were created.

I'd need the whole methods code to see if you were committing any of those errors.

Alex Flynn,

Thank you for your answer.

I looked at the number of zero is good and is ok. Perhaps the date format is falls. In the transaction code BAPI, when I try de methods, I get de dd.mm.yyyy format. But in the order table, de format is yyyymmdd. In my code, I have get the dd.mm.yyyy format.

This is the whole methods code. I'm sorry but de comments is in french.

If you want the complete code, give me your Email address and I send you the complete code.

p.s. I have use this architectur to use the other BAPI function and it goes.
