Common Data Definition properties

Data Definitions inherit common module identity/state and add shared data-lifecycle behaviour.

Property	Type/default	Effect
File Connection reference / FileConFIDS	module GUID / empty	Links a File Definition to its File Connection
Disable string trim / DisableStringTrim	Boolean / true	Controls base string trimming behaviour; distinguish it from file-specific TrimStrings
Truncate strings / TruncateStrings	Boolean / false	Allows values to be truncated to field sizes; can hide source-data quality problems
Active/runtime request/response/data state	runtime only	Assigned by Flow/API execution; not a persisted configuration field

The Definition owns data views/fields and is referenced by identity. Changing its shape can invalidate Maps, Reports, parameters and scripts even when the module still saves. Validate every dependent design and a representative runtime Flow.
