Unable to send WP_PLU to outbound

Dear Friends,

I have created Article maser records and I could able to send the WBDDLD idoc through Assortment initialization programs

But when I tried to send the the WP_PLU and WP_ EAN, there is no idoc generates.

Partner profile maintained for the Customer of the store

Message type set in outbound.

What is missing here so that I can send the WPPLU idoc outbound.

Thanks is Advance.

Regards,

SR
