Hi Ravi,

This is related to Memory Allocation Sequence for all Work Process Types.

Please check the roll area parameters in your system. If the size allocated to roll area is low then background jobs will not finish successflly.

Please check the all other parameters also related to Memory Allocation.

ztta/roll_first: Defines the first part of the roll area that is allocated to dialog process

ztta/roll_area: Defines the total roll area per work process

rdisp/roll_SHM: Defines the size of the roll buffer

rdisp/roll_MAXFS: Defines the size of roll buffer and roll file

em/initial_size_MB: Defines the fixed size of extended memory

ztta/roll_extension: Defines the user quota for extended memory

abap/heap_area_dia: Defines the limit for the amount of local memory allocated to dialog work processes

abap/heap_area_nondia: Defines the limit for the amount of local memory allocated to non-dialog work processes

abap/heap_area_total: Defines the limit for the total amount of heap memory allocated to all work processes

Hai,

Since your problem is with Roll_area, you have to increase ztta/roll_area to 6.5MB in case of UNIX.

If you are in WINDOWS increase ztta/roll_area to 2MB.

Also check the parameter ztta/roll_first is set to 1MB. (default)
