Extraction via Abap Class leads to SYSTEM_IMODE_TOO_LARGE

Hi all,

nead some help in that case :

the extraction / append i implemented for the Datasource 0FI_GL_4 by an ABAP Class

leads to a Dump called "SYSTEM_IMODE_TOO_LARGE".

What i do is to instantiate the Object within the standard include and i do also call the

Garbage Collector manually after every precessed Datapackage.

like : CALL METHOD CL_ABAP_MEMORY_UTILITIES=>DO_GARBAGE_COLLECTION.

And I still get the Dump.

Any idea anyone ?
