Add memo/multiline column type support by abelmilash-msft · Pull Request #155 · microsoft/PowerPlatform-DataverseClient-Python

abelmilash-msft · 2026-04-01T19:06:40Z

Summary

Adds support for "memo" (or "multiline") column type, enabling creation of multiline text columns on Dataverse tables. Users can specify "memo" as a column type in client.tables.create() and client.tables.add_columns().

Changes

src/PowerPlatform/Dataverse/data/_odata.py

Add "memo" / "multiline" handling in _attribute_payload(), generating MemoAttributeMetadata with MaxLength: 4000, Format: Text, ImeMode: Auto

src/PowerPlatform/Dataverse/operations/tables.py

Document "memo" / "multiline" in create() docstring

examples/advanced/walkthrough.py

Add "new_Notes": "memo" column to walkthrough table
Include memo field in record creation with multiline content
Read back and display memo field in Section 4
Update memo with new multiline content in Section 5

tests/unit/data/test_odata_internal.py

test_memo_type() — validates MemoAttributeMetadata payload
test_multiline_alias() — validates "multiline" produces identical result

tests/unit/test_tables_operations.py

test_add_columns_memo() — validates memo type through add_columns()

README.md / SKILL docs

List "memo" in supported column types

Testing

620 unit tests passing
E2E memo walkthrough verified against live Dataverse (10 assertions):
multiline create/read/update, empty string, None, special characters,
long text (4000 chars), memo not mistaken for picklist label,
triple-quoted strings, clearing memo to None

Copilot

Pull request overview
