My model contains numerous expressions linked to various Excel files. When calculating the model, I frequently receive errors indicating issues accessing Excel data (screenshot of error provided). If I click "OK," save the model, and rerun the calculation, it progresses further until a similar error occurs with a different Excel file. This doesn't seem related to any specific file, as repeating the above steps eventually completes the calculation successfully, and it can happen to any file. This has been happening for a long time but just getting around to posting about it now. Could you please advise if there’s a way to resolve or mitigate this issue?

Thanks,

Matt
