How To Fix WXPB220 - Amount of memory space used is too large (see long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: WXPB - MAP Messages: SAP R/3 Enterprise Add-On

• Message number: 220

• Message text: Amount of memory space used is too large (see long text)

What causes this issue?

During manual planning you can navigate between the overview and period
screens and also to the screen between different characteristic levels.
As long as you do not leave the overview or period screen, the locked
data or total cells will be temporarily held in a program buffer (not
in the database) every time you change screens. This ensures that the
cells remain locked if you return to a screen with a certain
characteristics combination, for which cells were already locked. For
performance reasons, the buffer is initialized after the 100th screen
change. This will happen the next time you change screens.

System Response

The buffer will be extended with this screen change. If, the next time
you change screens, you navigate to a period or overview screen with a
certain combination of characteristics, in which you have already been,
the "memory" for the locked cells will remain intact.
If you change to a screen that you have not already displayed, the
memory will have to be initialized. Cells that were previously locked
will then no longer be locked.

How to fix this error?

Check whether your planning layouts can be reorganized so that a
smaller branch of the planning hierarchy is planned and the number of
navigations between different combinations of characteristics on the
overview screen is reduced for each layout.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message WXPB220 - Amount of memory space used is too large (see long text) ?

  SAP Error Message:
  
  WXPB220 - Amount of memory space used is too large (see long text)
  
  Cause:
  This error occurs when a program or process in SAP tries to allocate or use more memory than the allowed or available limit. It typically happens during report execution, data processing, or when handling large internal tables or datasets in ABAP programs. The system detects that the memory consumption exceeds the configured or permissible threshold, leading to this error.
  Common scenarios include:
  
  Processing very large internal tables or datasets.
  Inefficient memory handling in custom ABAP code.
  Insufficient memory parameters set in the SAP system profile.
  Long-running reports or batch jobs consuming excessive memory.
  
  
  Solution:
  To resolve the WXPB220 error, consider the following steps:
  
  
  Analyze the Program or Report:
  
  Check the ABAP code for inefficient memory usage.
  Avoid loading very large internal tables all at once.
  Use more memory-efficient data structures or process data in smaller chunks.
  Use COLLECT or SORT and DELETE ADJACENT DUPLICATES to reduce internal table size.
  Use database cursors or pagination techniques to fetch data in parts.
  
  
  
  Check and Adjust Memory Parameters:
  
  Review and possibly increase memory-related parameters in the SAP profile, such as:
  
  abap/heap_area_dia (heap size for dialog processes)
  abap/heap_area_nondia (heap size for non-dialog processes)
  ztta/roll_extension (roll area size)
  em/initial_size_MB and em/global_area_MB (extended memory parameters)
  
  
  These parameters control how much memory an ABAP program can allocate.
  
  
  
  Use SAP Memory Inspector Tools:
  
  Use transaction ST02 (Tune Summary) to monitor memory usage.
  Use SAT (ABAP Runtime Analysis) or SE30 to analyze memory consumption of the program.
  Use ST12 for performance trace including memory usage.
  
  
  
  Optimize Data Processing:
  
  If possible, filter data at the database level to reduce the volume fetched.
  Use parallel processing or background jobs to split workload.
  
  
  
  Check SAP Notes:
  
  Search for SAP Notes related to WXPB220 for specific patches or recommendations.
  Sometimes, specific kernel or SAP Basis patches address memory handling improvements.
  
  
  
  
  Related Information:
  
  Transaction ST02: Monitor buffer and memory usage.
  Transaction SM50/SM66: Check work process memory consumption.
  Transaction SE30 / SAT: Analyze runtime and memory usage of ABAP programs.
  SAP Memory Parameters: Adjusting profile parameters requires system restart and should be done by Basis team.
  SAP Notes: Use SAP ONE Support Launchpad to find notes related to WXPB220.
  
  
  Summary:
  The WXPB220 error indicates excessive memory usage by an ABAP program or process. The solution involves optimizing the program to use memory more efficiently and/or increasing the memory limits configured in the SAP system. Monitoring tools and SAP Notes can provide further guidance tailored to your system environment.
