Once they’re in PEX, you can easily code and tag transactions before they sync to Dynamics 365. They will then sync to Dynamics 365 with the correct expense account, vendor, class, department, location, and other mapped fields.

9
Click Save tag to finish.
  • The new tag appears on the Tag Manager page.

Create one tag for each Dynamics 365 field you map to a PEX tag (for example Vendor, Tax Rate, Class, Department, Location, Customer) using the same steps.
  • Your new tags appear in Tag Manager.

​
Dynamics 365 fields you can map to PEX tags

Dynamics 365 fieldDescriptionRequired
Expense AccountThe journal entry expense account. This account will be debited for purchases.Yes
VendorThe journal entry vendor. Only shown if “Create a Dynamics vendor for each unique merchant” is unchecked.No
Tax RateThe journal entry tax rate.No
ClassThe journal entry class.No
DepartmentThe journal entry department.No
LocationThe journal entry location.No
CustomerThe journal entry customer.No
Note:Only dropdown-type tags can be mapped to Dynamics 365 fields. Custom fields configured in Dynamics 365 are also supported and appear in the Mappings tables.

​
Where your tags appear

Once the tags are set up, you will also see them:
  • In the dropdown lists of the Mappings table so you can complete the mapping.
  • On the PEX transaction details screen, so you and your cardholders can tag transactions.
Tip:Enable the Sync Tag Toggle in the Dynamics 365 connector Mappings table. This automatically syncs field values from Dynamics 365 into PEX as tag options. For example, the values for a PEX tag “Expense Account” in Tag Manager will be populated with the names of your Dynamics 365 accounts.
