If you’re looking to find the Party Orders & Datings page in MySales:
1-Click on the party ref link (that’ll bring you to the the party summary).
2-Then click on any customer order (that will bring you to their order page) and click the ‘previous’ button at the bottom left.
3-That will bring you to their personal info page and click the ‘previous’ button at the bottom left.
That brought me to the Party orders and Dating page.
They will be updating shipping for past orders entered in mysales there.
