    Hi Abhinav,

    I think the issue over here is the use of for loop.You may be getting bulk data in for for loop and the logic may be taking long to execute.If provided the code then can get a more clear picture.

     

    Thanks

    Hi Abhinav

    To avoid this error,Please review your code and follow best practices to ensure that the heap limit does not exceed the maximum.

    Note -: Salesforce enforces an Apex Heap Size Limit of 6MB for synchronous transactions and 12MB for asynchronous transactions, and if you exceed that limit, you will receive an error message.

    Thanks

    Hi,

    Try to remove unwanted variables and loops. Optimize your code as much as possible, if not then try to change your logic if possible.

    Hop this helps.
