Need to fetch the "Planned dates" of the earliest Maintenance call number which is not released

Dear PM experts,

I am creating a custom report for next due date for a maintenance plan number. Next due date refers to the next Planned date which is having the status of "Scheduled  Hold" or I need to fetch the Planned date of the Call number from maintenance plan which is yet be released but its previous Call number has been released.

Example : Maintenance plan 111111 has 3 Call numbers and its status are given below from transaction IP10

Call Number       Planned date    Call date    Completion date   Scheduling type/ Status

1                         06.11.2014       06.11.2014                             New start  Called                 - Call number released and PM order created

2.                        06.12.2014       06.12.2014                             Scheduled  Hold                  - Call number yet to be released

3.                        06.01.2015       06.01.2015                             Scheduled  Hold                  - Call number yet to be released

Now in the report, i want to fetch the "Planned dates" of the earliest Maintenance call number which is not released

Please suggest me how to fetch this data for this issue
