3709113 - Error 'This Project ID exists. Enter another one' During Project Migration in SAP S/4HANA Cloud Public Edition

• Error message: "This Project ID exists. Enter another one"
• Occurs during migration using the Work Breakdown Structure (WBS) template.
• Error persists even when the project ID is not present in the system.

SAP S/4HANA Cloud Public Edition

1. Create a new project using the migration cockpit and select a template.
2. Run the simulation process.
3. Encounter the error message: "This Project ID exists. Enter another one".

In SAP S/4HANA Cloud Public Edition, the project header (Enterprise Project) and WBS elements are strictly separated objects during migration.

The migration file must not contain a Project Summary Task in the Work Breakdown Structure (WBS) sheet.

A Project Summary Task is a row where:

• The WBS ID is identical to the Enterprise Project ID

• The Parent WBS is empty

This row represents the project itself, not a real WBS element, and is not supported in Public Cloud migration.

Example of incorrect record (Project Summary Task)

This row must be removed from the “Work Breakdown Structure (WBS)” sheet:

Correct WBS structure for migration

In SAP S/4HANA Cloud Public Edition:

• Top-level WBS elements do not have a Parent WBS

• The project hierarchy starts below the project header

• Only real WBS elements must be included in the WBS sheet
