Batch management requirement cannot be changed; choose "Display errors".

when I want to change the batch management requirement indicator, an error message occurs: Batch management requirement cannot be changed; choose "Display errors".

And then I empty the stock of current period and previous period, but there is still an error message that said:

SD documents exist (orders or deliveries) that have not yet been

processed or that have been processed only in part.

So I'd like to ask why the SO of other plant can affect the material in this plant? how can I resolve this problem?
