    Hi @HSan1971,

    Simplest here is probably to use Generate Attributes. You can overwrite columns, so you would declare a column called "total day minutes", and the function would be:

    if(missing([total day minutes]),[total day charge]/0.17,[total day minutes])

    The if statement is used alongside the missing function to run the function if there's a missing value, else you state it should keep it's value.

    Hope this works for you.

    Best,

    Roland
