Hello,
1. Does changing a global dimension modify existing data?
No, changing a global dimension (e.g., from Purchaser to Area) does not modify existing data. It only changes which dimension is treated as global for new entries.
2. Why do some reports reflect the new dimension after the change?
Reports and filters tied to Global Dimension 1 or 2 automatically reflect the new assigned dimension. That’s because the system uses those global slots for filtering and displaying data, so once changed, any report referencing those fields will now show the new dimension.
3. Have there been any data changes or failed reports due to this?
By default, no data changes occur, but reports relying on the previous global dimension may fail or show incomplete data unless reconfigured. Custom reports or analysis views may need to be reviewed and updated to align with the new dimension.
4. What exactly does Business Central do when changing a global dimension?
It reassigns Global Dimension 1 or 2 to a different dimension code. This impacts new data entries only, and existing entries won’t be updated unless you run the Change Global Dimensions tool, which can optionally update historical data but must be run carefully with backups.
Hope this will give you some hint!
