createCancellationDocument Invoice

Good afternoon people,

I am having trouble canceling an invoice, I'm using atom B1 Object with "createCancellationDocument" method, I tried to help in any tips however found nothing following images.

Error:

I'm trying this in xml atom xform

<BOM xmlns="">

  <BO>

  <AdmInfo>

  <Object>13</Object>

  <Version>2</Version>

  </AdmInfo>

  <Documents>

  <row>

  <DocEntry>1286</DocEntry>

  <DocNum>1286</DocNum>

  <DocDate>20151105</DocDate>

  <EDocStatus>C</EDocStatus>

  </row>

  </Documents>

  </BO>

  </BOM>

I searched and did not find how to get the input xml to cancel, anyone have any example input xml, or could tell me how do I cancel an invoice.

Thank you
