There is no easy option on the user interface to delink participants registered to 2 CPs. One needs to recreate these participants as new and delete the linked one.
For example, the participant with PPID 10102 is registered to 2 CPs - ‘001-115’ and ‘BB1’
The participant was accidentally registered to the 2nd CP and now needs to be delinked. Below are the steps that need to be performed to delink the participants.
Export the participant data using export feature
2a. If there are any visits/specimens that are to be moved, then rename the older one to PPID_old so that one can identify the participant later on.
2b. If there are no visits/specimens collected for this participant then delete the participant and follow step 3
3. Create new participants using the exported file from step 1
4. For case 2a, move visits (along with specimens if any) from old participant (linked) to new by using bulk import. Refer to the page https://openspecimen.atlassian.net/wiki/x/DYBNGw for more details.
5. Delete the linked participant.
