I have a requirement where i am creating child records when lead is getting created.

On Lead conversion those records are getting attached to opportunity as child records

I have trigger to be fired on those child records after those are attached to the opportunity on lead conversion

I know triggers wont fire on cascade update.But i require an alternate solution for updating the count of child records on opportunity

Possible Suggestion/Solution #1

One solution is to create a rollup summary field in the parent object which is in your case is Opportunity. But the child objects to opportunity should be master-detail.

Possible Suggestion/Solution #2

You can create a custom field to store the count of related records associated to lead Object.

You can have a custom field on Opportunity and then map that count on lead against opportunity custom field using lead TO Account/Contact/ Opportunity Mapping.

during lead conversion, the count of related records would be mapped to opportunity custom field.
