what are SPA and GPA parameters?What the Purpose?Examples?
under ABAP Memory.

Answer Posted / rajeshwar rao

Within a main session, when ever you start an application
program, it opens up an internal sessions with in the main
session. The internal session has a memory area that
contains the ABAP program and its associated data. So when
ever you want to pass data between two internal sessions,
then you can use ABAP Memory (i.e import, export).


When comes to SAP memory (also known as global memory), if
the data has to be passed b/w two main sessions, we can use
SAP Memory(SPA/GPA Parameters). SAP Memory can also be used
to pass data b/w internal sessions.
