Introduction
Notepad++ is a free text editor with a lot of good functions to work on ABAP source code files. Several developers have shown how to improve your work with this editor. For example how to activate syntax highlighting and how to create a function list. That's great to read and write ABAP source code without using transaction SE80 or Eclipse - have a try, it's interesting to write source code without system assistance 🙂
As I played a little bit around with this tool and its possibilities, I found the "Run..." menu. With the help of this menu, you can run an application of your choice. But what would be an interesting application in connection with ABAP? After a little while, I had the idea of implementing a connection between Notepad++ and SAP Netweaver. So it would be possible to check syntax.
Please consider that this blog is just a technical demo. Replacing a great tool such as SE80 or Eclipse is naturally not a good idea. But it's a good chance to see a practical benefit of statement SYNTAX-CHECK in an own report 😉
Steps to implement
To build the bridge between Notepad++ and SAP Netweaver, we use "sapshcut.exe" of your SAP GUI and a small report. The report will read the ABAP source code file your are currently editing with Notepad++, checks syntax and shows output via ALV.
Steps on your PC
Define your own command in Notepad++ via menue "Run", entry "Run...". Use following command but set all values in angle brackets in accordance with your system environment (have a look at your SAP GUI). Pay attention to the parameter "pw". It's not necessary to use but handy when you test. Anyway it's insecure to save your password in clear text. You can replace shortcut "CTRL+F2" (toggle bookmark) with your own command thus it's more SE80 style 🙂
"C:\Program Files (x86)\SAP\FrontEnd\SAPgui\sapshcut.exe" -system=<SID> -pw="<password>" -client=<client> -user="<user>" -language=<language> -type="Transaction" -command="*ZNPP2SAP PA_FILE=$(FULL_CURRENT_PATH);"Here is an example:
"C:\Program Files (x86)\SAP\FrontEnd\SAPgui\sapshcut.exe" -system=IDS -pw="insecure" -client=001 -user="DEVUSER" -language=EN -type="Transaction" -command="*ZNPP2SAP PA_FILE=$(FULL_CURRENT_PATH);"Hint: I didn't find an easy way to edit my own command after saving. Perhaps I missed the function. But I found the file where commands are stored under "C:\Users\<username>\AppData\Roaming\Notepad++\shortcuts.xml". You can edit it but you have to restart Notepad++ to take notice of your changes.
Steps on your SAP Netweaver system
Copy the ABAP source code below into a report called ZNPP2SAP on your development system and activate it. Create a transaction for the report called ZNPP2SAP. That's all.
