Write to Cluster & User Exit.

Hi..

I try to create modification on PT60. I write my code in User Exit HRPTIM04, where my code is writing data to Cluster B2.

But unfortunately after Calling User Exit Function, there is Update proses (Perform Update_Buffer) in PT60 and re-write data from memory to Cluster B2 and i lost my first data (updated by PT60).

I try to search another User Exit after Update Buffer proses, but i didn't found it.

I need any advice for this problem.

Thanks.
