TTA COUNT/TOTAL of the child records
Hi all,
I have got two objects called clubs and registraions. I can register delegates to different clubs. On the club object I have got a field called spaces_booked. What I would like to do is to display number of delegates who have booked for that particular club.
Is there a way to achieve that? I can't seem to find the COUNT function on the salesforce.
Help please.
Registraions Object
Registered
- Mr Dole
- Mr Smith
Club Object
Spaces_Booked
- 2
-------------------
Regards,
2 Options:
1 - If you link them as child-parent, you can use Rollup Summary fields to count. Definetely the easier.
2 - Alternatively you will have to do this via triggers.
Hope that helped,

Hi there,
Thanks for your reply. I tried converting that look up filed (Club) to a master detail type but keep getting the following error message:
You cannot create a new Master-Detail relationship on an existing custom object if records already exist. You must first create a Lookup relationship, populate the lookup field with data in all records, and then change the relationship type to Master-Detail.
I also deleted all the records on both club and registration objects but still getting the error message.
Thanks for your reply anyway.
Regards,
I deleted all of the records of the Custom Object that has the Lookup field, and then made the switch to Master-Detail. If that doesn't work, why not delete the Lookup field and create a new Master-Detail.
Hope that helps,
Sati
Hi,
Probably the problem lies in the deleted records still being in the Recycle Bin. Empty SF´s recycle bin and try again. It should work. Good luck,
