recursion problem in updating several lines of other table

Hello all,

I tried to apply recursion in the following situation:

In a session which contains header table and line table, whenever status of header changed to specific amount, go to the line table and change a CDF field's amount of all the lines and sequences related to that order.

It only changes the CDF of the first line and ignore the rest. I was wondering if this scenario is possible in LN development?

Thanks in advance for your help.
