SICF has wrong credentials after System Refresh

Symptom

• After a system refresh, the SICF nodes have assigned the wrong user/password data.

Environment

• All SAP System based on SAP NetWeaver platform

Components

• WEBSERVICE- Web Service Configuration (SOAMANAGER)

• SICF- HTTP Service Configuration (SICF)

• RFC- RFC Connections (SM59)

Cause

• The data that is required to calculate the system fields are removed from the buffering in the shared memory. However, in certain constellations, data relating to the system fields are still stored in the shared memory. This may cause the system fields to be calculated incorrectly in subsequent requests.

Resolution

• Call function module ICFBUFFER_INIT.
