Click Process Credits, and the new soft credits will appear under the tab.
The new soft credits will also appear in the list of transactions under Donations > Transactions > Search & Manage. Each listing of soft credits will have a link to the original transaction for easy access and record-keeping.
NOTE: If the listing is not a soft credit, it will say False under the Linked column. If it is a soft credit, like below, it will show the ID number of the transaction the soft credit is linked to.
