Hi Hari,
You are correct, we didnt hae UJ0_NAME_RULE in BW 701.
I followed the same steps that Kalyan had mentioned in his steps. There were no additional steps to it. I just removed the restrictions from 'INVALID_DIM_NAME_CHAR' in UJA_VALID_VAL and then went to UJ0_NAME_RULE and removed the restrictions.
What are the errors you are getting specifically?
Thanks,
Abhishek
