Essbase models that are enabled for duplicate member support will have a validation error when the model contains a non-string dimension element with a delayed key binding. Essbase Studio Server cannot generate the concatenated key binding required at deployment time.
To work around this, you can clear the “Duplicate member name support” option in the Essbase model. But if this is not feasible, these are possible solutions:
Set the key binding in the dimension element that contains the delayed key binding.
Set the key binding for the dimension element in the hierarchy where it is used.
