Reads an org-wide mapping stored by an Entity Mapping Put — for example “which target-system id does source employee A123 have?” — and puts the value in an assign. A miss puts nil there.

​
Configuration

  • Domain — the entity kind to look up in.
  • Namespace — optional label naming the mapping set within the domain. Must match the Entity Mapping Put that wrote the mapping; leave blank for the default set.
  • External ID — the mapping key, with {assign_key} interpolation (same syntax as Flow Log). Takes precedence over the assign below.
  • External ID assign — alternatively, name an assign whose raw value is the key.
  • Output assign — where the looked-up value lands.

​
Tips

  • The node always passes through. To branch on the result, follow with a Flow Guard on the output assign — bail when value is defined skips work that’s already mapped; bail when value is nil skips work that needs a mapping first.
  • A miss overwrites the output assign with nil, so stale values from earlier iterations can’t leak through inside a Flow Each.
