How important is SAP SNP deployment? What is the purpose of deploying the SAP SNP? These are the things we will discuss below.
How is SAP SNP Deployment?
Before we tackle how to deploy SAP SNP, let us learn first what SAP SNP is. SAP SNP is a system that acts as an interface between the SAP ERP and other applications, such as SAP CRM, SAP SRM, etc.
It acts as a bridge between the two applications.
What Is The Purpose Of Deploying SAP SNP?
The purpose of deploying SAP SNP is to make it easier for developers to join different applications. In the past, everything must be coded in ABAP.
If you want to create an application that will connect to another application. Then you have to write a lot of code in ABAP.
With the SAP SNP deployment, you can just create a manifest file for every application you want to join. This manifest file will contain data about the application.
Then you can use this manifest file to connect your application with another application using SAP SNPs.
How To Deploy SAP SNP?
Now we will see how to deploy SAP SNP using at least three different methods. You can select any one of these methods for your deployment process.
Here are the three methods of deploying SAP SNP:
- Deploying using Netweaver Application Server (NAS)
- Deploying using Smart Component Architecture (SCA)
- Deploying using Web Dynpro Component Architecture (WDCA)
As far as we know, deploying using WDCA is more popular than NAS and SCA. It is because it is easier to use and it has more features than NAS and SCA.
Deploying Using NetWeaver Application Server (NAS)
NetWeaver Application Server is a Java-based server that provides support for Java technologies such as Java EE, JMS, and RMI. It also supports various protocols such as HTTP, HTTPS, and TCP/IP.
When you use NAS to deploy your SAP SNP, basically what you are doing is that instead of calling ABAP libraries from your Java code. You are calling NAS-based functions from your Java code.
Basically what NAS does is that it will call ABAP libraries from your program. Then return the output to your program so that your program can use this output for its purpose.
So this way your program will be able to communicate with ABAP. Without writing any ABAP code or calling any ABAP library directly from Java code.
But if you write any code in ABAP or call any ABAP library directly from Java code. Then NAS won’t help you because NAS doesn’t have any knowledge of ABAP.
So if we use NAS to deploy SAP SNP, the first NAS will call ABAP libraries from your program. Then return the output from ABAP libraries back to your program.
This way your program will be able to read the output from ABAP libraries directly from Java code without writing any ABAP code or calling any ABAP library directly from Java code.
This is what happens when you deploy SAP SNP using NetWeaver Application Server (NAS).
