Autogenerated IDs for crosswalks
Learn about autogenerated IDs for crosswalks representing different data sources.
For crosswalks, the behavior depends on whether the value was sent.
| Value was Sent | Reaction |
|---|---|
| No | Generate a new crosswalk value |
| Yes | Use the crosswalk value that was sent |

SEQUENTIAL Configuration

"type": "SEQUENTIAL",
"rangeStart": 12,
"step": 3
}Reltio Connected Cloud doesn't check if the generated value doesn't overlap the existing attribute/crosswalk values which were not produced by the generator, The only way to make sure that there won't be any conflicts with existing IDs is to analyze existing values and configure appropriate generation pattern and — in the case of the SEQUENTIAL generator — starting value and increment.
