Users may encounter an issue where changes made to MPN (Manufacturer Part Number) ranks in ActiveBOM are not retained after saving. Upon reopening the ActiveBOM document, the previously set ranks appear to be lost. This behavior is typically caused by invalid characters in the component descriptions, which prevent the ActiveBOM from being properly saved.

MPN Ranks and Favorite Suppliers Not Retained
After setting MPN ranks and selecting favorite suppliers in ActiveBOM, users may find that these changes are not saved. When the document is closed and reopened, the previously configured ranks and supplier preferences are missing.
Why This Happens
The issue is caused by invalid characters in the component descriptions. These characters interfere with the save process, preventing ActiveBOM from writing changes to disk.
What to Do
To resolve this issue:
- Remove invalid characters from component descriptions.
- Reapply MPN ranks and favorite supplier selections.
- Save the ActiveBOM document again.
How to Do It
- Open the ActiveBOM document.
- Review component descriptions for any unusual or unsupported characters.
- Edit the descriptions of the components to remove or replace invalid characters.
- Reapply MPN ranks and favorite supplier selections.
- Save the ActiveBOM document.
- Close and reopen the document to confirm that changes are retained.
Additional Notes
- Invalid characters may include special symbols, control characters, or unsupported Unicode characters.
- Standardizing component descriptions can help prevent future save issues.
