Generate Rows generating duplicate records, how to avoid it

[BalaBhaskar]

I have a requirement like if there is no record for a perticular date, it should be filled with previous date data.

Ex:  

Date                      Value

2024-01-01        10
2024-01-02        23
2024-01-03        43
2024-01-05        12
2024-01-06        65
2024-01-07        23
2024-01-08        45
2024-01-11        54
2024-01-12        34

So, I dont have data for 2024-01-04, 2024-01-09, 2024-01-10. These records must be filled with previous days data

My expectation is: 

Date                      Value

2024-01-01        10
2024-01-02        23
2024-01-03        43

2024-01-04        43
2024-01-05        12
2024-01-06        65
2024-01-07        23
2024-01-08        45

2024-01-09        45

2024-01-10        45
2024-01-11        54
2024-01-12        34

I used Generate rows tool to generate the records, but it is generating duplicates. Help me in this regard!
I have attached sample workflow

We can calculate the Date Diff between current row and next row and use the combination of Generate Rows and Formula tools to do it.
Here is a weekly challenge  that is similar with your question.
