I am trying to save files from the app using a unique compound name, for this I have created a composite key, which is calculated in one column and is referenced in another virtual column whic is actually the key column. In conclusion what we want is that the loaded files are recorded with the compound name plus the name of the field and sort of automatic timestamp, however this is not happening. For example, the last file loaded will be grab with the following name โ190703ciudadalternativaredes@gmail._6006317240172830498.Programa.034225โ, which does not follow the defined scheme. What can we do to solve this problem?
