Data not printing in adobe form

Hi,

I have copied standard interface PTRV_EXPENSE_FORM to Z interface and assigned the Z interface in my Z form. I have created an internal table GT_HISTORY in Global data. I moved the data from existing table to Global internal table GT_HISTORY in initialization event. Input parameter is IT_HISTORY and ouput parameter is GT_HISTORY for Initializtion event.

Data from GT_HISTORY is not getting printed.

I kept breakpoint in FM generated by the form. Data is being moved to GT_HISTORY table but still it is not getting printed.

I would like to know, do we need to assign this Z interface somewhere?

Thanks in advance.
