SAPAlias
Attribute | Description | Mandatory / Optional | Allowed Values | |
---|---|---|---|---|
protocol | Supply the connection protocol | mandatory | rfc | to use the RFC protocol |

Parameters
SAPRFCAdapter
Name | Type | Direction | Description |
---|---|---|---|
connectionString | String | in | Supplies the connection string (optional). |

Client Connection Options
Via the SAP alias and the configuration descriptor you can get the protocol and the connection string. This string looks like:
name1="value1" name2="value2" ...;
Example: client="100" lang="D" ashost="10.160.99.122" sysnr="00" trace="1"
The connection string must be provided in the following format:
<optionName>="<optionValue>"<space><optionName>="<optionValue>"...
If you do not conform with this pattern, this can lead to options not being recognized. Those errors won't be reported, but affect SAP behavior (e.g. you'll get a SAP connection error with CALL_FUNCTION_SIGNON_INCOMPL
).
Pay attention that the names are not case-sensitive but the values are. Depending on the RFC server, some of these names are fix and some of them are optional.
List of Available Options
Name | Description | Values | Default | |
---|---|---|---|---|
ABAP_DEBUG | RFC with ABAP debugger | 0 | without Debugger | 0 |
1 | with Debugger | |||
ASHOST | Host name of a specific application server (R/3, No Load Balancing) | |||
CFIT | Conversion Fault Indicator Token. This flag determines substitute symbol for received Unicode characters, which could not be converted by the RFC library. | non Unicode systems 0x23, Unicode systems 0xfffd, or defined by environment variable RFC_REPL_CHAR | ||
CODEPAGE | The given codepage is to be used for this connection (Default is either 1100 or set by RfcSetSystemCodepage or is set by SAP_CODEPAGE environment variable). Could be rather useful if the sapgui should be started with codepage differs from 1100. | |||
COMM_CP | When communication has to be established between an Unicode Library and a Non Unicode system, all char like data will be converted into codepage which matched to logon language before send them. This codepage is called communication codepage. The effect of this method is that the Non Unicode System is sure to talk an system with communication codepage and not with an Unicode system. Usually the RFC Library determines automatically the communication codepage. Using this option it is possible for the programmer to set the communication codepage directly. This option is only active in the Unicode version of the RFC library. | |||
DEST | Destination in saprfc.ini if working with saprfc.ini. If the RFC server is an R/2 system this destination must also be defined in the 'sideinfo' for the SAP gateway. | |||
GROUP | Name of the group of application servers (if using Load Balancing) | |||
GRT_DATA | SAProuter connect data for SAPGUI when using RFC with SAPGUI. /H/...... : the whole router string for SAPGUI. /P/password: If the password for the SAPGUI connection is not the same as the one for the RFC connection. | |||
GWHOST | Host name of the SAP gateway (if server is R/2 or External) | |||
GWSERV | Service of the SAP gateway (if server is R/2 or External) | |||
ICCE | Ignore Character Conversion Errors. This flag determines the runtime behavior of the RFC library concerning character conversion. If this flag is 1, the concerned API will not exit with error, but replace the character which could not be converted with CFIT defined token. | 0 | not ignore | 0 or defined by environment variable RFC_IGNORE_CONV_ERROR |
1 | ignore | |||
IDLE_TIMEOUT | Inform the Web Application Server to close the connection after idle time in seconds. | |||
LCHECK | Logon check at OPEN time | 0 | without check | 1 |

MSSERV | Service of the Message Server (if using Load Balancing) | |||
NEWPASS | Changes the password during logon On SAP system kernel older than 46C the password is sent in clear text on the network! | |||
PCS | Partner's Char Size. The RFC-library determines automatically the partner's char size at open time (using logon check) or at first call time (without logon check).
| 1 | Non Unicode | 1 |
2 | Unicode | |||
R3NAME | Name of the SAP system (if using Load Balancing) | |||

ALIAS_USER | An alias user name, could used instead of user or even together with USER. If both USER and ALIAS_USER are used, than they have to be match. |
EXTIDDATA | Contains valid external user's ID of an external authentification system. User name is optional. External ID is to be defined in the backend (SAP-System). |
EXTIDTYPE | Defines the kind of external identity. Valid only with EXTIDDATA. Follow values are not allowed: ID, NT; DN, CA, X, HX. Additionally, RFC Library provides the feature to retrieve MYSAPSSO2 certificate from the backend after successful logon. |
GETSSO2 | Request to create a cookie version 2 using given password and user name. If the value is 1, the cookie will be generated from user and password values given by USER=user and PASSWORD=password in the same connect_param string. Instead, user and password X.509 certificate could be used. If the RfcOpenEx call ended successfully, the generated SAP cookie version 2 can be retrieved via RfcGetTicket API. |
MYSAPSSO | SAP Cookie Version 1. Will be used instead of user and password for logon to backend |
MYSAPSSO2 | SAP Cookie Version 2. Will be used instead of password for logon to backend. In this case, user name is optional. |
X509CERT | An X.509 certificate will be used instead of password to logon to SAP System. In this case, user name is optional. |
