What upload modes are available for hierarchy maintenance in SAP MDG, and how do they behave for synchronized and non-synchronized hierarchies?
SAP MDG hierarchy maintenance supports five upload modes: Delete All, Overwrite or Add, Move Children, Replace Nodes, and Remove Edges. The safest choice depends on whether you need to delete everything, add missing edges only, re-parent children, replace a parent’s direct children, or delete only explicit edges; synchronized hierarchies can impact multiple hierarchies because technical edges are shared.

SAP MDG hierarchy upload offers five modes, each with a different impact on existing edges and child assignments. The most important distinction is whether the hierarchy is synchronized or non-synchronized, because synchronized hierarchies can share technical edges across multiple hierarchies. The guide also shows that Delete All is broad, Overwrite or Add is non-destructive, Move Children re-parents nodes, Replace Nodes rebuilds direct children, and Remove Edges deletes only the explicit edges.
Process flow
- Identify the hierarchy that needs to be maintained.
- Determine whether it is synchronized or non-synchronized.
- Determine whether it is version-dependent or version-independent.
- Select the upload mode according to the required operation.
- Define the file structure with the correct header, higher-level node, and lower-level node entity types.
- Include the hierarchy name where required by the selected mode and hierarchy type.
- Upload the file.
- Review the effect carefully, especially for synchronized hierarchies where one technical edge may occur in multiple hierarchies.
