Send Message Extended (Distribution List)

Hi,

I am trying to send an email using send message extended system function.

In "To Recipient" : I passed a distribution list number (Since i want to send message to multiple people based on the list of address numbers in the distribution list)

                              Created a distribution list using P02150, (Under one parent number, there are other address numbers with structure type as EML)

                              In "To Recipient", selected "Grouped Distribution List" & passed the parent number & structure type.

But still it is not sending email to any of the members in the distribution list.

If I Pass only single address book number, it is sending emails.
