Hello
This is my first SCN blog and i would like to share some of the important concepts used by most of the technical consultants in SAP.
Some of them may be project specific but i thought it would be good to collect them all at one place.
| Concept | Transactions |
| Data dictionary objects | SE11 |
| Reports | SE80 or SE38 |
| Module pool programming | SE80 or SE51 |
| BDC | SE80 or SM35 |
| Scripts | SE71 |
| Smart forms | SMARTFORMS |
| Classes | SE24 |
| Function modules | SE37 |
| Bapi | BAPI |
| Lsmw | LSMW |
| Customer exits | CMOD |
| Badi | SE19 |
| Implicit and Explicit enhancements | SE80 or SE19 |
| BTE | FIBF |
| Validations | OB28 |
| Substitutions | OBBH |
| Custom infotypes | PM01 |
| Workflow | SWDD |
| Adobe forms | SFP |
| Query | SQ01 |
These are just some common concepts and relevant transactions used by me or most of us,
i would like to know if you do use some other tools or concepts for development.
Note: I tried to collect only concepts which needs to be developed, hence didn't mention other concepts like
performance tools (ST05 or SE30), transport mechanism (SE09 or SE03) etc ...
Any suggestions are always welcome. 
Thanks and Regards,
Gautham Vangaveti.
