When a calculation file is loaded, the software searches the database for combinations of id and name of a dataset. If the item is not found the inputs are changed to ‘own input’.
Therefore, calculations files that are opened by other installations of the software with a different database, will show ‘own input’ and give the correct results.
If you change the name of entries in the database the same will happen. You will see ‘own input’ in old files that used this entry and they will use the original data.
