MS DynamicsNAV Web service index out of bounds

Question

Hi Im having problems with Microsoft Dynamics NAV 2009 R2 Web Service!

There is a webMethod given called OrderGoodsInsert which needs parameters lLanguageId [int], lRec [Text 250] [100]

lRec should be a string array with values such as these

1. "Document Type"
2. "Document No."
3. "Line No." - (empty at creation)
4. "Insert User"
5. "Modify User"
6. "Type" [0 – „”, 1 – G/L Account, 2 – Item, 3 – Resource, 4 – Fixed Asset, 5 – Charge (Item)]
7. "No." – item code
8. Quantity

Using c# code I try to call the method that is added as a web service reference to my project. The code:

string[] arr = new string[8];
arr[0] = "1";
arr[1] = currentDocNo;
arr[3] = "SU04";
arr[5] = "2";
arr[6] = item.Code;
arr[7] = item.Amount;
arr[2] = "";
arr[4] = "";

navWS.OrderGoodsInsert(1062, arr);

But when I do I get

A first chance exception of type 'System.Net.WebException' 
occurred in System.dll
A first chance exception of type 'System.Web.Services.Protocols.SoapException'
occurred in System.Web.Services.dll

The error is that index out of bounds

Am I doing something wrong?

Answer 1

The problem was that the developer of the WS made changes and did not send out a new documentation. One more string was needed in the array which represented the shelf the item is on.

Answer 2

Your OrderGoodsInsert method looks on the SOAP Definition like this

<sequence>
  <element minOccurs="1" maxOccurs="1" name="lLanguageId" type="int"/>
  <element minOccurs="1" maxOccurs="unbounded" name="lRec" type="string"/>
</sequence>

So it's expecting an string for the variable lRec and not a string[].

Try to convert the Array to one single String with a delimiter.

navWS.OrderGoodsInsert(1062, string.Join(";", arr));

But i am not sure which one is the right delimiter for NAV WebServices.
