SAP Note 26880 - SAPcomm: No link to the SAP System

Symptom:

The component "SAP" of the communications server SAPcomm cannot make the link to the SAP System. Error entries in the log file (lyymmdd.sap) of the "SAP" component: E1521 Back from CMINIT: RC=20
E1506 CPI-C function CMINIT returns 20 = CM_PRODUCT_SPECIFIC_ERROR
E1508 > Additonal SAP CPI-C error information: .....RC=472....
E1707 Cannot open destination

Cause and prerequisites

The component "SAP" of the SAPcomm communications server searches for the entry, in the sideinfo file, DEST=. is taken from the SAPcomm configuration or from the "environment" (see SAPcomm manual or also Note 14930). However, this entry does not exist in the sideinfo file.

Solution
Add the entry DEST= to your sideinfo file. Alternatively, if a suitable entry already exists under another name, change the SYSTEM parameter in the SAPomm configuration file. Documentation on SAPcomm: "SAP Communications Server." Manual: Documentation for maintenance of the sideinfo files: "SAP Communication: Configuration."
