Reason for navigational and display attribute in BPC dimension?

Hello everyone,

I'm just analyzing an error in a process chain and released that we have different attribute types in a BPC dimension.

Our dimension has about 20 properties. Each of them have 10 till 60 characters except for two properties, which have 255 characters.

If I view the attributes in RSA1, the two properties with 255 characters are display attributes the other attributes are navigational.

What's the reason for this and how can I change the display to navigational attributes?

Thanks,

Julian
