Lusid.Fund.Writer

Type	Read/write	Author	Availability
Data provider	Write	FINBOURNE	Provided with LUSID

Providing you have sufficient access control permissions, the Lusid.Fund.Writer provider enables you to write a Luminesce SQL query that either creates or deletes funds in LUSID.

Note: By default, Lusid.Fund.Writer cannot add properties to funds. To do this, you must first configure Lusid.Fund.Writer to 'inline' properties. See how to do this.

You must construct a valid table of data to write, one fund per record. Lusid.Fund.Writer lists the fields (columns) available to populate with values for each record, and has a set of parameters to help you construct a valid table. Note a fund references a particular ABOR and no other fund can reference the same ABOR.

Your query can use the WriteAction field to perform one of the following operations:

• Upsert a fund; that is, create a fund if it does not exist, and update just its inlined properties if it does. Note you cannot currently update the core data fields of an existing fund. This is the default operation if you omit WriteAction.
• Insert a new fund.
• Update just the inlined properties of an existing fund.
• Delete a fund.

Basic usage

@table_of_data = <select-statement>;
select * from Lusid.Fund.Writer where toWrite = @table_of_data;

Query parameters

Lusid.Fund.Writer has parameters that help you construct a valid table of data to write.

Note: The ToWrite parameter is mandatory and used to actually write the table of data into LUSID.

To list available parameters, their data types, default values, and an explanation for each, run the following query using a suitable tool:

select FieldName, DataType, ParamDefaultValue, Description from Sys.Field where TableName = 'Lusid.Fund.Writer' and FieldType = 'Parameter';

Data fields

Lusid.Fund.Writer lists the fields you can populate in your table of data to write.

Depending on the operation you want to perform, the following fields are mandatory to include in the table of data:

Operation	Specify using...	Mandatory fields	Notes
Upsert	'Upsert' as WriteAction (or omit)	FundScope FundCode AborScope AborCode InceptionDate YearEndMonth YearEndDay DisplayName	No other fund can reference the same AborScope and AborCode.   You can only update inlined properties of an existing fund, not core data fields.
Insert	'Insert' as WriteAction		No other fund can reference the same AborScope and AborCode.
Update	'Update' as WriteAction		You can only update inlined properties of an existing fund, not core data fields.
Delete	'Delete' as WriteAction	FundScope FundCode

To list all available fields, their data types, whether fields are considered 'main', and an explanation for each, run the following query using a suitable tool:

select FieldName, DataType, IsMain, IsPrimaryKey, SampleValues, Description from Sys.Field where TableName = 'Lusid.Fund.Writer' and FieldType = 'Column';

Write errors

We recommend examining the results of every write query using one or more of the WriteError, WriteErrorCode and WriteErrorDetail fields.

For each record in the table of data to write, Lusid.Fund.Writer returns an error code. If the operation is successful, the error code is 0. If unsuccessful, a positive error code and explanation help you discover why LUSID considers the operation invalid.

Examples

Note: For more example Luminesce SQL queries, visit our Github repo.

Example 1: Create a fund

The referenced ABOR must already exist and be referenced by no other fund.

@data_to_write = select 'Funds' as FundScope, 'Growth' as FundCode, 'Abor' as AborScope, 'Standard' as AborCode, 
#2024-01-01# as InceptionDate, 'Fund for growth' as DisplayName, 12 as YearEndMonth, 31 as YearEndDay;

select * from Lusid.Fund.Writer where ToWrite = @data_to_write;

Example 2: Create a fund with share class instruments

Share class instruments are optional but any referenced must already exist either in an explicit instrument scope or in the default (system) scope.

@shareclasses = values
('LUID_00003DTJ', 'MyShareclassInstrScope'),
('LUID_00003DTI', 'default');

@data_to_write = select 'Funds' as FundScope, 'Growth' as FundCode, 'Abor' as AborScope, 'Standard' as AborCode, 
#2024-01-01# as InceptionDate, 'Fund for growth' as DisplayName, 12 as YearEndMonth, 31 as YearEndDay,
column1 as ShareClassInstrumentLusidInstrumentId, column2 as ShareClassInstrumentScope from @shareclasses;

select * from Lusid.Fund.Writer where ToWrite = @data_to_write;

Example 3: Delete a fund

Specify 'Delete' as WriteAction to delete a fund.

@data_to_write = select 'Funds' as FundScope, 'Growth' as FundCode, 'Delete' as WriteAction;
select * from Lusid.Fund.Writer where ToWrite = @data_to_write;
