Material determination issue in DIP profile

Hello,

I had configured the DIP profile to get the 'Material costs' and 'Labor costs'. I was able to see the Labor costs in DP91. However, the Material costs are not flowing over in DP91. Can someone please tell me if I am missing anything? Also, while maintaining the set for 'Materials', how can I do it if the Materials have special characters (Material # A123456-1 or A1234-1). Please see the attached config screens.

Thanks.
