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.
