Under AIX, the heap memory may not exceed 256 MB. Extensive background processing jobs that exceed this limit may allocate SAP extended memory; however, the extended memory may be used up.

Try to solve the problem using the following procedures. Note the sequence they are given in. If the problem cannot be corrected with one of these procedures, try the next procedure.

• For reports started in the background, use more restrictive selection criteria to process smaller amounts of data.
• On servers that process large jobs, administrate lists and simple tables using the ABAP paging system. To do this, use the system profile parameter abap/use_paging.
