Answered: Create Debtors - error

I had same problem, it was problem with DebtorGroupHandle, you give array for the function (debtorGroup_GetAll)

$DebtorGroupHandles = $client-debtorGroup_GetAll()-DebtorGroup_GetAllResult-DebtorGroupHandle;

but function whants one entry Like

'DebtorGroupHandle' => (object) array( 'Number' => 1 ),

 

it worked for me :)
