Steploop and table contol is inevitable in certain
transactions. When we run BDC for such transactions,
we will face the situation: how many visible lines of
steploop/tablecontrol are on the screen? Although
we can always find certain method to deal with it, such as
function code 'NP', 'POPO', considering some extreme
situation:
there is only one line visible one the screen, our BDC
program should display an error message.
(See transaction 'ME21', we you resize your screen to let
only one row visible, you can not enter mutiple lines on
this screen even you use 'NP')
