I'm stuck here till.

I want details on parallel between "Penerimaan" and "Potongan" as shown in the detail report header above.

how?

funtion penerimaan:

IF {Command.Plus_Minus} = "+" then

    formula = {Command.DS_Desc}

end if

funtion potongan :

IF {Command.Plus_Minus} = "-" then

    formula = {Command.DS_Desc}

end if
