Without knowing the specific errors you are receiving, I'm not sure anyone is going to be able to say whether the errors you are receiving will result in consolidation issues or not.
Here are a few common examples of dimension vertical extensibility issues that will definitely result in consolidation issues:
- Attaching an extended member to a parent member of the inherited dimension
- Having incompatible properties between the extended member and the base member to which it is attached in the inherited dimension. Eg - defining an extended member with a plug account, but using a different or no plug in the base member of the inherited dimension
- Constraints that are looser in the extended members than the constraints defined for the base member of the inherited dim to which it is attached. This is really just another variation of incompatible properties, of which there are many others to consider.
