* The request is escalated to a data manager, who grants an exceptional approval and commits the request: This option is correct because when there are not enough approvers available to satisfy the terms of the approval policy, the request is escalated to a data manager after exceeding the defined number of approval notifications. The data manager can then grant an exceptional approval and commit the request.
* The request is escalated to an application owner, who changes the approval policy to require fewer approvers, at which point the request is committed: This option is correct because when there are not enough approvers available to satisfy the terms of the approval policy, the request is escalated to an application owner after exceeding the defined number of approval notifications. The application owner can then change the approval policy to require fewer approvers, and then approve and commit the request.

Explanation
Mapping nodes across applications are required when applications share data but have different dimensions or different granularity. For example, if a source application has a product dimension with four levels and a target application has a product dimension with three levels, you need to map the nodes from the source to the target to determine how the data will be aggregated or disaggregated. Similarly, if a source application has a monthly time dimension and a target application has a quarterly time dimension, you need to map the nodes from the source to the target to determine how the data will be summed or averaged. Mapping nodes across applications are not required when applications have common dimensions but usedifferent prefixes or suffixes for member names, because this can be handled by node type converters or property derivations. Mapping nodes across applications are not required when applications share an external connection, because this does not affect the dimensionality or granularity of the data.
