Hi,

Use runtime analysis (SE30) and execute the transaction or the report. Usually the display transactions are used. Go only to the screen where the data you want to find exist and come out of the transaction. If you want to find which tables are updated by a create transaction, then execute the entire transaction for document posting. After executing the transaction and coming back to runtime analysis, analyze the result. All the tables, read or written by the transaction are listed under the Tables heading. From the table description, try to identify the table which may contain the required data. You can choose a particular table for which all the access made are displayed. From there you can go to the actual source code where the access was done by selecting an entry and pressing button source text.

Hi Venkat,

If you paste your code then we can tell you at what places it require changes and why they are required.

Hi,

to save the system memory u can :

1. clear or refresh of internal tables after they use

2. work areas of internal tables also cleared immidately

after they use.

3. use internal tables with out default work area ie use types

for that.

4. do the program->extended program check

so that it shows unused variables means these

variables vasting system memory and remove them.

we can only control

ABAP and database timings

System we cannot control.
