Client	Enter the three-digit numerical key to uniquely identify the client in your SAP ECC to which you want to connect.
User	Enter the name of the user that connects to SAP ECC at runtime to post the interface objects, such as IDocs.
Password	Enter the password for the runtime user. NOTE As of release ECC, the password strategy for connecting to the system has changed; the password is case sensitive. You can use special characters. Before connecting to an SAP ECC system prior to ECC.
Language	Enter the two-digit language key in ISO code format. Enter, for example, EN for English or DE for German. Refer to your SAP ECC system for the language key table.
SystemNumber	Enter the two-digit number that identifies the SAP ECC system. This is the instance number you find in the login properties of your SAP ECC system.
maxConnection	Define the maximum allowed number of connections from SAP Business One integration framework to SAP ECC.
gatewayHost	Enter the hostname or IP address of the SAP ECC gateway host, for example, iwdf9349.wdf.sap.corp. To check the gateway host in SAP ECC, call the smgw transaction and choose Goto → Parameters → Display.
gatewayServiceNumber	Enter the gateway service number of your SAP ECC system. By default, the gateway service number is sapgw<system number>. If you cannot connect to SAP ECC using the Test Connection function, enter the service number instead. To check the gateway host in SAP ECC, call the smgw transaction and choose Goto → Parameters → Display.
senderPartner	Enter the logical system that you have created for SAP Integration Framework 2.0 in your SAP ECC system, for example, B1I176550A. You have created this entry in following the section 6.3.1.3 Defining a Logical System for SAP Integration Framework 2.0. For RFCA communication the SAP Integration Framework 2.0 server is the sender partner.
senderPort	Enter the port for the RFC destination, for example, B1I176550A. Apart from using the port key, which is for example A000000009, you can access the port using the name of the RFC destination that you have created for the SAP Integration Framework 2.0 server in SAP ECC. To check the port key for the RFC destination, use the WE21 transaction in SAP ECC. In the Ports section, expand Transactional RFC and identify the port by the description for the logical system.
receiverPartner	Enter the logical system of the SAP ECC client. You have identified this entry in section 6.3.1.1 Checking the Logical System for the SAP ECC Client. For RFCA communication the SAP ECC client is the receiver partner.
receiverPort	Enter the port number of the RFC destination for your SAP ECC. Enter, for example. EH3CLNT100.  Apart from using the port key, which is for example A000000009, you can access the port using the name of the RFC destination for your SAP ECC client in the SAP ECC system. To check the port key for the RFC destination, use the WE21 transaction in SAP ECC. In the Ports section, expand Transactional RFC and identify the port by the description for the logical system.

6. Choose Save and in the RFCA section choose Test connection.

1. To start SAP Integration Framework 2.0, choose Start → All Programs → Integration Framework for SAP Business One integration → Integration Framework.
   
2. To log on, in the Administrative User interface, enter the user name and password.
   
3. Choose SLD, select the system entry for the SAP ECC client and choose Edit.
   
4. In the RFCP section, do the following:
   

Field Name	Description
ApplicationServer	Enter the host name or IP address of the SAP ECC application server, for example iwdf9349.wdf.sap.corp. To receive this information, contact your SAP ECC administrator.
Client	Enter the three-digit numerical key to uniquely identify the client in your SAP ECC to which you want to connect. This can be, for example, 100.
User	Enter the name of the user that connects to SAP ECC at runtime to post the interface objects, such as IDocs.
Password	Enter the password for the runtime user. NOTE As of release ECC, the password strategy for connecting to the system has changed; the password is case sensitive. You can use special characters. Before connecting to an SAP ECC system prior to ECC.
Language	Enter the two-digit language key in ISO code format. Enter, for example, EN for English or DE for German. Refer to your SAP ECC system for the language key table.

maxConnection	Define the maximum allowed number of connections from SAP Integration Framework 2.0 to SAP ECC.
gatewayHost	Enter the hostname or IP address of the SAP ECC gateway host, for example, iwdf9349.wdf.sap.corp. To check the gateway host in SAP ECC, call the smgw transaction and choose Goto → Parameters → Display.
gatewayServiceNumber	Enter the gateway service number of your SAP ECC system. By default, the gateway service number is sapgw<system number>. To check the gateway host in SAP ECC, call the smgw transaction and choose Goto → Parameters → Display.
programID	Enter the program ID for the SAP Integration Framework 2.0 RFC destination in SAP ECC. To check the program ID in SAP ECC, call the sm59 transaction, expand the TCP/IP connections section, double-click the RFC destination for the SAP Integration Framework 2.0 server and choose the Technical Settings tab.  It is mandatory that the value of the program ID in the RFC destination and this value are the same. SAP ECC connects to the SAP Integration Framework 2.0 server using a program, which it identifies by the ID.
Unicode	If the SAP ECC system is a Unicode system, select true. Otherwise select false. To check the Unicode-related setup of your SAP ECC system, select System → Status… in the SAP System Data section in the Unicode System field.

5. To save your entries, choose Save.
   

The Test connectivity function is not available for the RFCP section, because SAP ECC initiates the RFC call to SAP Integration Framework 2.0.

You can test the connection in SAP ECC. It is a prerequisite for a successful connection test that you have assigned the system in SAP Integration Framework 2.0 to an active scenario.

To test the connection, do the following:

1. In SAP ECC, select the sm59 transaction.
   
2. In the TCP/IP connections section, select the RFC destination for SAP Integration Framework 2.0.
   
3. Choose Display and then Connection Test.
