CRM Opportunity not available in Sage 100 Sales Order Entry

When I create an Opportunity in CRM, sometimes I am able to pick that opporutnity in Sage 100 Sales Order Entry to tie the existing quote/order to the new opportunity in CRM.   But, sometimes when I do a search for the Opporuntity that I want to associate with the existing sales order with, the list is empty.  I haven't found what the pattern is that dictates whether the opporutnity is available to pick in Sales Order Entry or not.   The Sales Order is exisitng and I created the Opportunity in CRM afterwards.  Perhaps it is a timing issues where the Opporutnity needs to be created prior to the sales order?

Here is the opporutnity created in CRM:

And here is where I am looking to connect that opportunity to a sales order:

Any thoughts or guidence would be appreciated.
