Hi Gurus,
Our users are getting error during mass printng of invoices (say like 100 of them). The error says "SAP System Message: Extended Memory Layer (EM) error". But they are able to mass print in groups of 10 or 20.
I am sure somewhere there is a memory bottleneck. But where? I cannot understnd how come extended memory area has to do anything with this.
Any explanations, anybody? and the method/parameter to adjust this?
Thanks,
Javed
Hello Javed,
The error indicates a problem with the memorymangement of the extended memory,
Parameter to look at is em/global_area_MB.
In order to solve the error you have to increase the parameter em/global_area_MB as per
Note 103747.
This parameter has to be set in the instance profile of each
application server. After this the instance have to be restarted
For more information:
em/global_area_MB - Size of the extended global memory area in MB
This value specifies the maximum size of the part of the extended
memory (see also parameter em/initial_size_MB) that is reserved
for global data, that is data that is not specific to user or
work process. The amount of data is relatively small (at the most
a few percent of the total extended memory pool), since in the
global area only administration data for internal communication
between R/3 kernel components (task handler, enqueue) is
stored.
This should help to resolve the extended memory error.
See also the following note that can be also useful for you:
425207 - SAP memory management, current parameter ranges
I hope this helps you.

Blanca

Thanks Blanca,
However, Extended memory has been setup to a very large value already in our system (60 GB). AND I am not able to convince myself that a mass print request (however large it may be) can cross 60GB limit. Even user context memory is 6GB which itself is huge.
Somehow I do not understand the underline activities after a print is fired. Is it possible that these output request are queued up somewhere and that queue has a limit? or something like that? Unfortunately, I could not find anything to this regard in SAP notes or forums.
Appreciate your help!!!
Regards,
Javed
