Parameter
ABAP/HEAP_AREA_DIA
Short text
Heap Memory Limit for Dialog Work Processes
Parameter Description
Specifies the maximum local process memory (heap, malloc) that can be allocated to a single dialog work process. The aim is to limit the size of a user context if required.
Parameter Unit
Bytes
Default Value
2,000,000,000 (2 GB)
Default Value
As long as the memory requirement for individual user contexts is unknown, we recommend specifying a high value. However, if you wish to avoid problems resulting from user contexts being too large, you can use this limit to terminate a user context if it exceeds a certain size. To make the best possible setting for this value, you need to know the maximum memory requirement allowed for user contexts. The value 0 overrides this limit.

Are other parameters affected or dependent?
The parameter value only takes effect if it is lower than the value specified for ABAP/HEAP_AREA_TOTAL. ABAP/HEAP_AREA_TOTAL restricts the total local process memory in all work processes.
Operating System Restrictions
The maximum local process memory is also subject to limits determined in the operating system by configuration settings or architecture. You can determine some of these limits by means of the test program ‘memlimits’. A value only takes effect if it is lower than the maximum size specified by the operating system.
