MEMORY ID U CAN MAKE IN TABLE <b>TPARA</b> USING SM30

Memory ID refers to the use of ABAP Memory which is specific to an external session(window). When you have multiple sessions open, each of the concurrent sessions(windows) has it's own ABAP Memory.

ABAP Memory can thus, only be used to share data between internal sessions, that is programs/transactions that have been called by other programs/transactions in the same external session(window).

ABAP memory is cleared(and correspondingly all Memory IDs), when the session is deleted(window is closed), not when the transaction ends. The only exception to this rule when a transaction ends through the use of

LEAVE TO TRANSACTION

which is when the entire external session is flushed and the ABAP Memory is cleared.

basically there are 2 memory

SAP Memory and ABAP Memory

Sap memory.

set parameter/ get parameter

Hi Kunal,

The purpose is to allocate a cluster/memory area to YOUR SESSION. Once you allocate a memory, you can dump the values which are required across different programs.

Say Report 1 wants to pass PLANT paramter to REPORT 2.

SO Report 1 will save it on the Memory ID. Report 2 will retrieve the Plant from that Memory ID.

Its a Unique key to refer to a memory area.

Best regards,

Prashant
