Batch Characteristics in Goods Receipt

Dear Experts,

I want to restrict GR, that system should ask for one Manufacturer before posting and for the same, I have created Batch Characteristics and Class and assign to Material. In CT04, I applied for ‘Required Entry’.

During GR, System is showing all Manufacture list and asking to select one Manufacturer. But due to presence ‘No Entry’ option (by default 'Checked') in MIGO Classification, the system by default picking this option and allowing to do GRN Post.
