I needed to renumber objects for Skyrr Payroll addon and found on Mibuso an old renumbering tool. I downloaded it and installed. I corrected the bug and created an import function for Excel worksheet.
The Excel worksheet has the object type in column A, object ID in column B, object name in column C, object caption in column D and the object new ID in column E. The first row is the header row. I simply copied my object list from Object Designer and worked out my new ids in Excel.
After importing this Excel worksheet I have a list of new and old IDs in NAV.
If any of the new IDs is an old ID, you will need to renumber first from the old ID to temporary ID and then do another renumbering to the new ID.
I create two sheets in my Excel workbook to solve this.
This renumbering tool does not support Pages and I did not need that support in this case.
