All,
I'm trying to figure out a way to dynamically populate a column as it passes through a data flow task. My data source is Excel 2007 and the first row of data has data in the say, column B, and then rows 2-50 let say contains blanks for this column. I want to grab this date on the first row and assign it as my column value for all subsequent rows.
I've tried doing this in a script transform and assigning the value to a variable but it seems like it can only write to the variable after all rows have passed through it. This is where it get's a little more complicated. Let's say on row 51 there is a new value in column B. Now I'd like to use this new data as the column B value for rows 52-100. If the value couldn't possible change, I'd be good with setting this variable at the end of the script transform, but alas no.
So how can I dynamically set this value in column B as the transform is rolling through the data?
Example:
Original Data
ColumnAColumnB
15/1/2016
2
3
4
5
65/2/2016
7
8
9
10
Final Transform
ColumnAColumnB
15/1/2016
25/1/2016
35/1/2016
45/1/2016
55/1/2016
65/2/2016
75/2/2016
85/2/2016
95/2/2016
105/2/2016
Thanks for any guidance anyone can provide.
