Where free tools help
Tools like KoSIT are strong for schema-level output validation. They are ideal when you only need to verify whether a produced XML payload matches a formal format.
Where operational teams need more
In real SAP projects, root causes often come from mapping, master data alignment, and business-rule interpretation. That requires remediation context, not only pass/fail output.
