how to see and transfer availability time or expiry time of each batch from ECC to APO and view it in APO when batch is transferred?

3. Shelf life and maturity time of stocks             

If indicator 'Planning with shelf life' is set in the product master, stocks should bear explicit shelf life data. That is only possible if the material is to be handled in batches in the R/3 System and if every batch is provided with an expiry time (end of shelf life). Optionally you can also maintain the availability time (end of maturity time). For the transfer of this data into the APO System, please refer to the following notes:               339576, 391018, 535422.              

This transfer is only possible if 'CDP' is determined as classification system.

can I get more explanation on this
