AR Invoice Transaction DFF Setup to for user selection of Project and Task Number

Hi,

I have setup the AR Invoice Transaction descriptive flexfield with 2 segments:

1) Project Number. For this I defined a Value Set with Table validation so the user can pick up the Project Number at transaction level entry.

2) Task Number: For this I defined a Value Set with Table validation so the user can pick up the Task Number at transaction level entry. For this I choose:

Application: Projects

Table: PA_TASKS

Table Columns: TASK_NUMBER

I have an issue with the definition above because I want the list for Task Number segment to be display only with the Task Numbers LOV for the Project selected in segment 1 (Project Number) and with my definition the lov included all the tasks numbers.
