Thanks all for your replies. yes i have check the system and Batch Level is defined on Material Level.
Jurgen actually this question is not related to expiry exactly. just for
good understanding of question i put question like this.
in classification tab we have one parameter "Release Status" which have value
X or Y. X means release and Y means Not release.
We are using this parameter for Auto batch determination purpose. if value is Y then this
batch will not come in auto batch determination.
same thing happend to this parameter. when we change value of this parameter in classification in one plant it is refelecting on all plants. which i dont want.
i hope you get my point.
