Merge Perspectives/Translations in BISM Normalizer

When merging models, it may be useful to create selections from a source perspective without losing existing selections that were already there in the target.

The same applies to translations for a culture.

Consider the following comparison taken with the merge perspectives option checked.

Note that the differences in the target object definition are highlighted in grey instead of the normal red. This is to indicate that they will not be removed.

After applying the update (assuming FactRate is still in the target database) and re-running the comparison, the following definitions are displayed.

For the purpose of the comparison, the definitions are considered the same because an update would have no effect.

However, if the merge perspectives option is unchecked and the comparison is re-run, the definitions are considered different as shown below.

A subsequent update will remove selections for the FactRate table.

This works basically the same way for cultures. When the merge translations checkbox is checked, existing translations will not be removed. Different translations for an object property that is both in the source and target cultures will be overwritten.
