Batch job - 'Zero' value is not loading in Target Syatem

Hello All,

Could any one please clarify me whether '0' value will be replaced in the Destination, if destination is having some number.

Ex Target Planning Area is having some number (ex: 20) for particular CVC and Source Planning Area is having Zero value for the same CVC.

Now after the Planning Area copy job runs, whether Target CVC will be loaded with Zero value or will it have same old value(ex: 20)  ??

Thanks in advance.

Regards,

Kishore
