If you are importing credit card expenses in the system using the upload transactions feature, then you first need to map the account name for each user.
Step by step process:
1. Log in as Admin
2. Go to users and click on the Edit icon
3. Under the expense tab, update the cardholder number and then click on "Update User"
The cardholder number needs to be unique for each user.
This could be the name of the user or the card number. The only requirement is it must map to what you have in the transaction file. The system uses this field to look up expenses for each user.
