Scheduling Aggrement Creation Profile

Hi all,

I need to send JIT scheduling lines to my vendor with IDOC.

But I need to send only differences.

For example;

1st JIT says A material 10 qty 1st January

2st JIT says A material 15 qty 2st January

IDOC should be created for just A material with 15 qty but It is creating 10+15 qty with two lines in it.

Thanks for your replies.
