Journey of an ABAP program

Whenever you talk about performance analysis or performance tuning we always analyze majorly the response time and one major part of this is LOAD and GENERATION Time. Understand it this way , we can broadly categorize any program into two phases :- 1. Where it exists as SOURCE CODE , that means that since the system installation programs are never executed.  In this phase the source code is saved in the REPOSRC table , formerly it was stored in  D010S table till SAP Web AS6.40 2. Where the code is executed after installation are stored in another table. this phase can be termed as  LOAD PHASE   . So basically the phase where programs that are executed are saved. The executed program are saved in the REPOLOAD   table , formerly known as D010L table till SAP WEB AS 6.40. Make an additional note here, Each time an ABAP or its dependency is changed, it needs to be compiled again. We can use SGEN command to execute the source codes in advance , it should be executed after every Support Pac
