Extended Memoy error while mass printing

Former Member

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:

I hope this helps you.

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!!!

Javed

Thanks Juan.. I was hoping you to step in soon

Even I searched for the error logs and surprisingly there is no entry corresponding to this error! It's just a popup that appears with the error description when user tries to mass print.

I am lost!
