During mapping development you might use connection attributes, and during run time you can change the attributes without changing the connection attributes.

The CDM folder path and entity name must be valid when you override the default file system name, CDM folder, or entity name. Otherwise, the mapping fails with an error.

You can override the file system name when you select the file system name override option. For example, if you configured connection attributes for file system name

cdmsd

, CDM folder path

demo/model

, and the entity name

ff_cdm

, you can change the attributes during run time. You can select the file system name override and specify the system name

cdmsd_prod

. However,

cdmsd_prod

must have the same CDM folder path and the entity name that you specified in Microsoft CDM Folders V2 connection.

You can also override the filename when you select the CDM folder override option. For example, if you specified the CDM folder path

/folder1/default.manifest.cdm.json

in the Microsoft CDM Folders V2 connection to read from

manifest.cdm.json

file, you can choose to read from

model.json

file during run time.
