Process order vs Batch Size

Hi Expert :

the MD04 propose to us some planned order for some packed Finished product later the planner convert them to process order in some way we have one process order for each day .

the quantity of process order is calculated to satisfy the demand of Each day meaning each day we have a diffrent quantity .

in other side the local rule for warehouse : Batch can't exceed 27 Ton meaning if i have to produce 60ton i should have 3 batch ( 27+27+6 ) intead i have only one process order .

my question which parameters i should change in some how to have 3 process order limited each 27 Ton from MD04 intead of 1 process order with 60ton

Thank you very much
