Standard Characteristics LOBM_LFDAT for delivery date

Dear Experts

I have updated the Update standard Characteristics and the characteristic "LOBM_LFDAT" for the delivery date was created ..

I have created a new class and assigned the charcteristics to it then I assigned the class for the material ..And I have Activated Batch Classification for Goods Movements in IM for Mvt 101 and 561to be"Classification carried out in background (all batches)"

The problem is when I post a goods receipt I click on classification button in the batch tab .. there is no LOBM_LFDAT and when I look into table AUSP I found no records for this characteristics .. its like never hold the delivery date automatically

Please Advice as it very important
