I have two input fields one for material other plant.
I have done select option for material (because i need to give more then one material number)
I have parameter for plant .
I need to validate plant corresponding to material number.I have done it for single material input.
How can i check for one more material number in select option.
i give 3 material number by selection option:1001,1002,2001
material number 1001 and 1002 belong to plant 001 but material number 2001 belong to other plant.
how can validated.?
