Distribution in Planning Sequence

Hi Guys,

I have created a layout with the Following Buttons (1. Variable Screen and 2. Distribution)

The Distribution button has a planning sequence.

When the user enter the Variable and log in to the layout and make Adjustments. if he press the Distribution.

Then Distribution happens.

After the Distribution is done if the user still on the Layout and Clicks the Variable Button and make changes (Eg Changing the Plant from 6000 to 6100) and then clicks the Distribution. then Distribution is not happening.

But if the user logs back to and clicks the Distribution. then it Distribution.

Could some let me know if they have faced similar issues.

Any Suggestion would be great.

Thanks

PS
