table export failed: [4001] attribute inconsistent;joinConditionjoin3_0_join3_1_concat

Hello Experts

When trying to export an Schema I'm getting this error:

table export failed: [4001] attribute inconsistent;joinConditionjoin3_0_join3_1_concat

I tried to do it by the user interface on hana studio.

This is an schema that shares some virtual tables on another Schema.

maybe that is the cause for this error

hope you'll be able to help me

Best Regards
