Unable to increase Extended Memory in SAP ECC 6 EHP 5

When we try to increase extended memory in RZ10 -> Basic maintenance -> Memory Management for any of the parameters ztta/roll_extension, abap/heap_area_dia, abap/heap_area_total, etc. the system gives an error message like "dialog / max local memory greater than maximum 2047 MB". Where is this limit of 2047 MB being picked up from and how can it be increased? We are unable to increase memory due to this.

Stuck where? Have you considered using the "Extended Maintenance" option to change the parameters instead of the using the "Basic Maintenance"?, If your task is to change the ABAP memory parameters then consider doing it from RZ10 like suggested above.

What is the size of the ABAP buffersize set on the system? Have you tried changing the profile parameter values using the "RZ10 - Extended Maintenance" instead of the "Basic Maintenance"? Check this note 983566 - RZ10: Buffer size for ABAP programs in basic maintenance

Previously abap/buffersize was set to 600000. I changed it to 3000000 but now I'm getting a new warning when I go into memory management in basic maintenance:

ABAP Programs factor 10 greater than default 300000 KB


The original error is still there after doing this.

OK. The note is only referring to the ABAP buffersize. I believe it is applicable for other parameters as well but I can be wrong as well.

>>ABAP Programs factor 10 greater than default 300000 KB<<

Based on what you have said the default values are taken from the kernel default. and the note isn't valid for your issue. The default value for abap/buffersize on my system is 300000. So the pop-up comes if you try to change the parameter to a value higher than the default value. In that case you will get those error messages as long as the values are higher than the default value. I always changed profile parameters from RZ10 - Extended Maintenance permanently and using RSMEMORY for temporary change.
