In this SAP Press book chapter excerpt, find an introduction to SAP ERP integration with other enterprise systems, and learn how SAP ERP can optimize a variety of business software. So far in the first three chapters of this book we have studied an overview of SAP business suite applications and the Net. Weaver Application Server ABAP and Java technology foundation that it runs on. In this chapter we will study the central role the SAP ERP system has in an organization and its network integration into the organizations enterprise infrastructure, as well as to the external systems outside the organization and the SAP support infrastructure. This chapter covers various communication and integration technologies that bind different SAP ABAP and Java based applications, along with the third party enterprise solutions, external vendors, and SAP support organization into an enterprise wide SAP solution adding value and driving the business needs of an organization. This chapter is also intended to give an overview to enterprise architects as to how a SAP solution would fit into an enterprise wide architecture. Figure 4 1 illustrates the integration scenarios that could come into play with the implementation and operations of a SAP ERP system for a hypothetical SAP customer. The remaining sections of this chapter will use this hypothetical scenario to explain the common integration scenario groupings and the underlying communication protocol and standards used by SAP.

Rfc Connection In Sap Pdf DownloadOne of the following basic network and communication standards is at the heart of the different integration scenarios with the SAP ERP system. Let us look into the details of each of the following protocols and standards. TCPIPIn SAP business applications, network communication is with the Transmission Control ProtocolInternet Protocol TCPIP standards. During the system build phase, the required IP address is assigned to the host and necessary configuration is performed where a particular SAP business solution is planned to be installed.

SAP Javabased applications use a different set of network ports. Table 4 2 lists the most important ports and rules for using the SAP Javabased applications. In UNIX operating systems, the services file maps port numbers to the named services. This entry gets there during the time of the SAP installation of a given business solution. The services file location in a UNIX operating system is etcservices. If, for any reason, the service file entry is missing, then the communication between the SAP applications will be lost and can be restored by adding an entry manually. Usually it requires a root user permission to make any changes to the etcservices file. RFCRemote Function Call RFC is SAPs communication interface. RFC communication between SAP business solutions involves an RFC client and an RFC server. The RFC server provides function modules. RFC clients call one of the function modules, pass on the data, and get a reply value back from the RFC server. Setting Up an RFC Connection. Transaction code SM5. RFC connections or to alter an existing connection. Several types of RFC connections can be set up in SAP systems using SM5. RFC connection types 3 connects to another ABAP system and T TCPIP Connection are most often used. One Ok Rock This Is My Budokan Concert. The following procedure is used to set up an RFC connection type 3 in SAP systems. Use transaction code SM5. SAPGUI command line see Figure 4 2. Select the connection type ABAP Connections, and click the Create icon. This will open the screen shown in Figure 4 3. Enter the following fields to complete the RFC destination configuration RFC Destination Name of the RFC destination of the target ABAP system. Description Enter a text description. Target Host Enter the hostname or the IP address of the target ABAP system. System Number Enter the target ABAP system number. Figure 4 2 Initial RFC creation screen. Click the Logon Security tab, and enter the logon information Client, User, and Password. After this, save your connection entries by clicking the Save button, as in Figure 4 4. If you receive any message window saying the user can log in to the remote system, just click OK and continue. Your connection entries will be saved. The next step is to test if our RFC connection is working properly. Click the Connection Test button at the top of the screen. You will see the screen shown in Figure 4 5 if all of your connection entries are correct. This is a basic connection test. This does not test the authorizations of the user who initiated the connection. In order to test if this user has the authorizations to initiate an RFC connection and successfully log in to the target system, go back to your RFC connection parameters screen and use the menu option Utilities Test Authorization Test. This test should be successful as well before you can proceed with your work in the target ABAP system or use this connection for noninteractive login by application. You can use the similar procedure to create RFC connections to different ABAP systems in your SAP system landscape. Please note that a successful authorization test is mandatory, as this test executes a user login along with password verification and authorization test in the target RFC connected system. A successful authorization test ensures that the RFC connection is completely ready for use in an application. Figure 4 3 RFC connection entries. Several other RFC connection types are used to integrate the SAP system landscape. The RFC connection type T refers to starting an external program using TCPIP. One example of such need in a SAP system landscape integration scenario is within the SAP Process Integration application. In this scenario the Process Integration PI ABAP components integrate with the SAP PI Java component using this connection type. Gateway connections remain open because of firewall ABAP Connectivity. Purpose. The purpose of this wiki is to explain why gateway connections could remain open when making a connection through a firewall. Overview The page will look at parameters that can be used to disconnect gateway connections and also reasons why firewalls may cause connections to remain on the gateway. Parameter Settings. Parameters gwgwdisconnect and gwkeepalive can be used to disconnect gateway connections. Parameter gwgwdisconnect This parameter specifies the time period after which an inactive gateway connection is to be closed. Normally, connections that have been created to other gateways are held until the other gatewayis closed. If no active connections exist to this gateway and the time frame has expired, then the connection to this gateway is closed. Value of 0 deactivates check. This check is executed a maximum of every gwmaxsleep seconds. Therefore, it does not make sense to set the value smaller than gwmaxsleep. Parameter  gwkeepalive Specifies the maximum time period in seconds before the system checks, using a ping, whether the partner is still alive when there is no data transfer across a CPIC connection. A value of 0 deactivates this check. Parameters gwgwdisconnect and gwkeepalive will close connections that have been OPENED by that gateway, connections ACCEPTED by the gateway will not be closed by these parameters. Also check parameter gwcloseroutes Connections that run over a Wide Area Network cause high running costs. Connections of this type are realized in an SAP environment using a SAProuter. The time period with which inactive gateway connections are closed is 3. This is too long for WAN connections of this type. Therefore, connections that use SAProuter are handled separately. If a connection that uses an SAProuter is not used, this connection is closed after a certain time. This period is determined by the value of this parameter. Value 0 deactivates the check of these connections. Connections between gateways in a Local Area Network LAN, which do not usually run through an SAProuter, are not affected by this parameter. This check is executed a maximum of every gwmaxsleep seconds. Therefore, it does not make sense to set the value smaller than gwmaxsleep. Firewall issues. Gateway connections may also remain because of firewall problems. The design of such firewalls is as follows. In other words, the firewall has two TCP connections. The TCP connection of gateway 1 ends in the firewall. The firewall opens up a second one to gateway 2 and directs the traffic internally and therefore has influence on the traffic to the correct TCP channels. Gateway 1 can cancel the TCP1 connection because of the gwgwdisconnect parameter. TCP1 is deleted. However, the firewall doesnt propagate the closing to the internally linked TCP 2 connection. In other words, the gateway 2 doesnt get informed that the remote gateway 1 closed the connection and therefore the TCP 2 remains in the gateway 2 display. If now, a new connection has to be setup from gateway 1 to gateway. TCP 3 and TCP 4 are built. TCP 4 appears in the gateway 2 display. If gwgwdisconnect applies, TCP3 will be deleted again, but TCP 4 remains in the display of gateway 2 and so on. This particular issue would need to be checked by the local network administrators to check the timeout parameter on the firewall. Related Documents. Related Notes. 74.
