Filling empty cells in a column with the last value
I am currently stuck in a problem to fill empty cells of a column with the last value that is stated in that column.
So I would like that the the cells of the column 'Cost Center Basis' are filled with the last stated value e.g. 'Kostenstelle/-träger: 1000010Bezeichnung: O001 General' until the next value is stated in the column.
Below is a sample of how the dataset looks like
And this is how I would like to have the result:
Does anyone know a way how to solve this problem either in Magic ETL or SQL? What's the best practise to solve this kind of problem?
Thanks in advance.
