can any one help me here. I am stuck this issue for long time.
There are two reasons why this might be happening:
Files are not copied to new models. So, if this is a different model, that file will need to be uploaded again.
Most likely, it is a permissions issue on the file. Meaning, if you uploaded the file and did not change the permissions to All or Administrations vs. Private File, then another person will not have access to the data within the file.
