Open the list of Environment Constants by choosing Edit >> Environment Constants from the NMM menu. Some entries may have a default value, which you do not have to change. Any entries in red must receive a value before you will be able to start the NLINK Server.
Your NLINK meta-database may not have all these entries, and/or may have additional entries specific to your configuration.
ADC | |
|---|---|
ADC TCP Port | TCP/IP port used by NLINK Server to receive requests. Use default unless there is conflicts with some other software using same port. |
Error Handling | |
EMAIL_SMTP_RELAY (or _SERVER) | Usually this can be blank. |
EMAIL_RECIPIENT_ADDRESS | Leave this blank to turn off error notifications. Otherwise enter a valid email address and NLINK will automatically send error notification emails to that address. If you do not see this Environment Constant, set the address directly in the System Properties. |
EMAIL_FROM_ADDRESS | If sending error notifications, enter a valid “from” address here. |
EMAIL_FROM_NAME | If sending error notifications, enter a name here. You can then use this information to filter the messages in the receiving email account. |
SAP (On-Premise Systems) | |
SAP_DESTINATION | Enter the destination (from the sapnwrfc.ini file) you want to connect to. |
SAP_CLIENT | Enter the SAP client number, just as you would if you were logging on through SAPGUI. |
SAP_USER_ID | Enter NLINK’s SAP user id. |
SAP_PASSWORD | Enter NLINK’s SAP password. |
SAP_LANGUAGE | Enter the SAP language, just as you would if you were logging on through SAPGUI (e.g., EN for English). |
SAP_USER_ID | If not using logon passthrough, specify an SAP User for NLINK to use for all communication. This is a required field, so even if you are using logon passthrough you will need to put something here (e.g., “notused”). If you are configuring your own transactions, you also need this user in order to run the SAP Wizards in the NLINK Configuration Module. |
SAP_PASSWORD | Enter the password for the NLINK User specified above, or leave empty if using passthrough. |
SAP_ALT_RFC_READ_TABLE | If your system needs to use an alternate RFC to get around the SAP floating point issue, enter the name of that RFC here (e.g., Z_RFC_READ_TABLE). If you don’t need the alternate RFC, leave this blank. |
SAP_DATA_DICT_USER_ID | Optionally specify an SAP User for NLINK to use for various technical communications, e.g., determing function module signatures. This may allow you to offload some technical authorizations to this single user instead of having to add them to all the business users. |
SAP_DATA_DICT_PASSWORD | Enter the password for the NLINK Data Dictionary User specified above, or leave empty if not used. |
SAP (S/4Cloud Systems hosted by SAP, or On-Premise Systems using SAP REST APIs) | |
SAP_SERVER_URL | Enter the base url for the SAP APIs, e.g., https://some.address.here:port/sap/opu/odata/sap/ |
AUTH_URL | Enter the public ping url, e.g., https://some.address.here:port/sap/bc/ping?sap-client=xxx where xxx is the client number |
SAP_LANGUAGE | Enter the SAP language, just as you would if you were logging on through SAPGUI (e.g., EN for English). |
