URGENT Fix SAP CPI Replication Issue

I have an SAP Cloud Platform Integration (CPI) iFlow that should move data from SAP S/4HANA to SAP C4C. After a recent round of setting changes, nothing is reaching C4C, so I need someone to jump in, trace the flow, locate the break, correct any mapping errors, and prove the messages post successfully.

Scope
• Examine the current iFlow, including the adapters, mapping steps, and any scripted groovy or XSLT.
• Identify why data is not being replicated—message monitoring shows successful pickup in S/4 but no payload in C4C.
• Adjust the affected mappings or connection parameters introduced during my recent configuration update.
• Test end-to-end until the target system receives and stores the data without manual intervention.

Deliverable
A working CPI iFlow with clear evidence (log screen-shots or trace IDs) that the data travels from S/4HANA to C4C and other way as well, plus a short note outlining the fix so I can keep it documented.

This is a small, urgent task; seasoned CPI troubleshooters who can start immediately and wrap it up quickly will be ideal.
