Summary :
This SAP Note addresses login issues encountered with Transaction OSS1, where error S1452 is displayed, indicating failure to connect to the OSS message server. The root causes identified include the absence of the 'lgtst' program or incorrect configuration setups. Users are advised to install 'lgtst' from the 2.2D CD into the executables directory. Additionally, correcting configuration involves ensuring appropriate Technical OSS1 settings and verifying the correct entries in /etc/services. Users experiencing connectivity failures should consult the Developer trace (Transaction ST11) to diagnose improper configurations or operational errors indicated by specific logs.
