Part6 : FPM OVP Application -Integrating Header LIST UIBB and ITEM List UIBB & Dynamically hiding ITEM LIST UIBB

Here the OVP application contains two list UIBBs. One is header UIBB which displays records form SCARR table and another one is ITEM UIBB which displays the records from the SPFLI table depending upon the row selected in the HEADER UIBB.

If more than one line selected in the header UIBB then the ITEM UIBB is set as invisible/hidden.

More than one line are selected in the header, So the ITEM UIBB is hidden.
