Batch operation fail for adding items in list

Question

i wrote a simple batch operation to test if i can add items to list, but i always get error.

            string batchFormat = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><ows:Batch OnError=\"Return\">{0}</ows:Batch>";

            string methodFormatTest = "<Method ID=\"1\"" +
                "<SetList>69f72fe7-1270-4e70-b3f5-11ed8ea05fea</SetList>" +
                //"<SetVar Name=\"Cmd\">Save</SetVar>" +
                //"<SetVar Name=\"ID\">New</SetVar>" +
                //"<SetVar Name=\"urn:schemas-microsoft-com:office:office#Title\">Text</SetVar>"

                 //"<SetVar Name=\"AuteurMetallurgyNuance\">Name</SetVar>" +
                 "<SetVar Name=\"IDMetallurgyNuance\">777</SetVar>" +
                 "</Method>";

            batch = string.Format(batchFormat, methodFormatTest);
            string batchReturn = web.ProcessBatchData(batch);

The erorr that i get is:

69f72fe7-1270-4e70-b3f5-11ed8ea05fea Invalid URL Parameter.

The URL provided contains an invalid Command or Value. Please check the URL again.

The question is, if the field is required and i dont fill it, can it cause an error?

Are this required? Save New

For testing i just want to add fill one field and save item.

UPDATE: I created an custom list, with only one field "Title" to test, so i execute the next batch :

            SPList list2 = web.Lists["Test"];
            string listGuid2 = list2.ID.ToString();
            string methodFormatTest2 = "<Method ID=\"1\" Cmd=\"New\"" +
                "<SetList>"+listGuid2+"</SetList>" +
                "<SetVar Name=\"Title\">New</SetVar>" +
                 "</Method>";

But i still get an error:

<Results>16032391-301a-4586-b6b3-2f0a6f0cfcae<Result ID="1" Code="-2130575350">
<ErrorText>Invalid URL Parameter.

The URL provided contains an invalid Command or Value. Please check the URL again.</ErrorText></Result>
</Results>

So help is still needed, if anyone has any suggestions!

UPDATE 2: I did test on an custom list and it added the title, now im trying this on my custim list, but it fails, it adds just empty rows, how is this possible?

Schema for the list:

 <Field ID="{93CF7259-2031-49B8-94E2-714A786F67AA}" Name="ID" Type="Text" DisplayName="ID" Group="V" Required="TRUE" ShowInNewForm="TRUE" ShowInEditForm="TRUE" Indexed="TRUE" />
      <Field ID="{A122D632-9D29-47FE-84A1-8609B94AF86C}" Name="Auteur" Type="Text" DisplayName="Auteur" Group="V" Required="FALSE" ShowInNewForm="TRUE" ShowInEditForm="TRUE" Indexed="TRUE" />
      <Field ID="{813B6A47-A0AC-46DD-912E-CBABE499D617}" Name="Reference" Type="Text" DisplayName="Reference" Group="V" Required="FALSE" ShowInNewForm="TRUE" ShowInEditForm="TRUE" Indexed="TRUE" />
      <Field ID="{776862E6-17F7-4CC6-9D70-6C63C6895887}" Name="TypeDo" Type="Text" DisplayName="Type Document" Group="V" Required="FALSE" ShowInNewForm="TRUE" ShowInEditForm="TRUE" Indexed="TRUE" />

And here is the code:

st

ring methodFormatTest = "<Method ID='775' Cmd='Save'>" +
                "<SetList>" + listGuid + "</SetList>" +
                "<SetVar Name='Cmd'>Save</SetVar>" +
                 "<SetVar Name='ID'>New</SetVar>" +
                 "<SetVar Name='urn:schemas-microsoft-com:office:office#Title'>titletitle</SetVar>" +
             "<SetVar Name='ID'>id</SetVar>" +
             "<SetVar Name='Auteur'>auteur</SetVar>" +
             "<SetVar Name='Reference'>ref</SetVar>" +
              "<SetVar Name='TypeDocMetallurgyNuance'>type</SetVar>" +
             "</Method>";
    batch = string.Format(batchFormat, methodFormatTest);
    string batchReturn = web.ProcessBatchData(batch);

So when i execute this it adds an empty row ... any idea?

Answer 1

To create a new item, You still need to specify the Cmd as Save, and provide New for the ID.

SPList list2 = web.Lists["Test"];            
string listGuid2 = list2.ID.ToString();             
string methodFormatTest2 = "<Method ID=\"1\" Cmd=\"Save\"" +     
    "<SetList>"+listGuid2+"</SetList>" +
    "<SetVar Name=\"ID\">New</SetVar>" +                
    "<SetVar Name=\"Title\">New</SetVar>" +                  
    "</Method>";

Answer 2

<?xml version=\'1.0\' encoding=\'UTF-8\'?>  
<ows:Batch OnError=\'Continue\'>  
    <Method ID=\'1\'>  
        <SetList>37c797c9-6feb-471e-a872-9407a760a21e</SetList>  
        <SetVar Name=\'Cmd\'>Save</SetVar>  
        <SetVar Name=\'ID\'>New</SetVar>  
        <SetVar Name=\'urn:schemas-microsoft-com:office:office#Title\'>abc</SetVar>  
        <SetVar Name=\'urn:schemas-microsoft-com:office:office#Cmt\'>abc</SetVar>  
    </Method>  
</ows:Batch>

This will insert values into two fileds namely Title and Cmd.
