Pending Item won't post.

I'm hoping a fresh pair of eyes will help me.  I have a pending item this simply won't post and gives me no indication about why

Here's the item

Group Control

Pending Item 1

Accounting Entries

I'm a bit concerned that there is only one line here.  But the group control says it is balanced.  I tried selecting Balance on the Group Action and no messages or errors

Group Action

Make sure AR Periods are open

Run AR Update

I dont' know what I'm missing.  Thanks in advance
