Hi Board,

I'm facing a issue in trigger where in i'm trying to perform a dml statement using List<sObject>.

It throws exception for me when i have more then 900 records in my list.

Error message is stated below:

System.TypeException: Cannot have more than 10 chunks in a single operation. Please rearrange the data to reduce chunking.
