Trigger email output at item level whenever sales order change

Hi All,

I customized the output type at item level ZOA6, and created one procedure which further I assigned it to my sales document type.

I assigned a requirement with my output type, and in that if sales document changes then it set sy-subrc =0 else sy-subrc =4. I maintain the condition record also.

And I assigned in output type to partner function CP in configuration.

But output type is not triggering, could you please let me know where I miss the configuration
