Classification for RG1 in J1I5

Hi Gurus

I need your help.

I have a scenario of textile company.

In one plant they have two notification where the production happens.

in Notification 29 all production happen for export & local sales

in notification 30 the production happens only for local sales.

User needs RG1 report notification wise or in the same RG1 report the material manufactured in both the notification should be identified separately.

To achieve this i am planning to have some Z classification like RMA & ROP for 29 & ZRMA & ZROP for 30.

So that for all the GR at 29 user will user ROP & RMA & For 30 user will use ZRMA & ZROP which i will use for separate reporting.

If some one knows that i can achieve this in some other way or this solution will not not work please advise me

Regards

Prabhat
