System name8 charactersA-Z, 0-9, _
Time zone8 characters
Run ID2,147,483,647The Automation Engine stores run IDs internally as 31-bit integers.
Tasks per workflowUnlimitedWorkflows with many tasks may cause high memory consumption & poor UI performance. (See the discussion on AE & AWI sizing.)
:PRINT line1024 charactersLines longer than 1024 characters are truncated at 1021 characters, and the last three characters are replaced with '...'.
Script lines per scripting tab32,767 (2¹⁶-1)See Process Pages in the AE documentation.
Generated JCL lines1024Can be increased if necessary by setting MAX_JCL_LINES job attribute.
Rows per static VARAUnlimitedLimited only by the underlying database.
Rows returned by SQL VARA500,000
(Default: 200)
Adjust via SQLVAR_MAX_ROWS in UC_SYSTEM_SETTINGS.
Rows returned by BACKEND VARA500,000
(Default: 200)
Adjust via BACKENDVAR_MAX_ROWS in UC_SYSTEM_SETTINGS.
# of search results returned: objects

20,000

(Default: 5000)

Adjust via GENERIC_SEARCH_LIMIT  in UC_SYSTEM_SETTINGS.

# of search results returned: active tasks

20,000

(Default: 5000)

Adjust via GENERIC_ACTIVITIES_LIMIT  in UC_SYSTEM_SETTINGS.

# of search results displayed in the AWI: active tasks

Unknown

(Default: 500)

Adjust via COMBINED_ACTIVITIES_LIMIT  in UC_SYSTEM_SETTINGS.

This setting affects the AWI only, not the JUI or Java/REST APIs.

# of search results returned: statistical records

(Default: 5000)

Adjust via GENERIC_STATISTICS_LIMIT  in UC_SYSTEM_SETTINGS.

XML export/import: file size30 MBCan be further limited using MAX_IMPORT_SIZE system setting. Exporting/importing very large XML files may cause high memory consumption & poor UI performance. (See the discussion on AE & AWI sizing.)
XML export: # of objects

1,000,000

(Default: 1000)

Adjust via MAX_EXPORT_COUNT  in UC_SYSTEM_SETTINGS.

If there’s a place in the documentation with all this info in one place, I could not find it. Please comment below if you know of an AE limit you’d like to contribute to the list.
