For PLD..automatic repete line depend on remain area of repetative area

For Print Layout Designer

Check how height of the repetative area (ex. height = 140)

After show of the item list (ex. for one A/R Invoice , there are only 2

items list showed .. by each item list line height = 20 ... So 2 lines

height used = 20*2 = 40 )

we create one empty line (height = 20) which we want the system will

calculate automatic how many time it will be repeted to show depend on

remain area of repetative area ( 140 - 40 = 100 , so remain height =

100 .. the empty line will repete automatic 5 times... 100 / 20 = 5 )

Anyone Please help .... I need the answer as fast as possible
