SNP Discrete Opt .... Lot Size is not correct

Dear Experts ,

I need some help with SNP Optimization execution ...... Actually i am executing discrete optimization , using weekly buckets.

For i.e

I have a demand with 100 pc ..... minimum lot size is 60 and max lot size is 62 .....

SNP should create two lots with 60 pc each one , but it is creating one lot with 60 and a second lot with 40 ..... It is considering last lot exact to fulfill demand .....

All PDS have discretization flag and the relevant parameters for discretization are set on OPT profile .....

I some setting missing ?

Please i need some help asap .....

Kind Regards

Mauricio
