Release Strategy

Hi Freinds

I had created a release strategy in one client say 100. I transported them to client 200 using tcode scc1. Initially i forgot to create characteristics and classes in 200. Then after transport i created the same. When I went to "Define Release procedures for Purchase orders and in that after selecting the release strategy and when i had clicked on the classification I am getting the following error

Error in classification (class Z_PO class type 032)

Message no. ME179

Procedure

Please check the specified class or class type in Customizing for the release procedure.

I once again retransported I am getting the same error.

Kindly Help.

Regards

Eldee
