One way to do this is to use an AttributeCreator where under Advanced Adjacent Feature Attribues is enabled. This way you are able to fill a row based on a value in a previous row.
Then use Conditional Value. How I configure this is to create a mockup with formulas in Excel, and then tranplant the logic from excel to the conditional value.
Hi
A possible way is, separate the data flow into two streams for LEEGSTAND = J or not with Tester and add sequential number attribute starting with 1 to the features passed the test with Counter (Count: LEEGSTAND_MAANDEN).
Alternatively, you can update LEEGSTAND_MAANDEN with a conditional value setting in AttributeManager, using @Count function like this.
Thanks

it looks difficult the make that possible
In that case, as
