Hi Robert,
You need to send an email to the FEI entries@fei.org with the message thaty you split the competition.
===================================================================
Hi,
Competition .. (2023_CI_...) has more than 100 declared starters and will be split in 2 groups -according the 2023 jumping rules- after the end of the competition.
Can you create the extra competition in the FEI database?
===================================================================
They will answer you with the code for the B competition.
This code you need to enter in the competition settings in the Headings tab,
Regards,
Thom Kerssies
