/**
* Inserts a document group to people list link record.
* 
* **Acceptable Inputs:**
*
* - @docgroupid bigint: Must be a non-null and non-empty valid identifier.
* - @peoplelistid bigint: Must be a non-null and non-empty valid identifier.
*
* **Return Values:**
* - ``@message nvarchar(1000) OUTPUT``: Descriptive status message of the procedure's execution.
* - ``@transaction_status nchar(50) OUTPUT``: Indicates the transaction status ('Good', 'Bad', or default 'Transaction not attempted').
*
* **Error and Exception Conditions:**
*
* - The document group id must be one which the connected user has view permissions for.
* - User Role Validation Fail: Returns 'No Permission' message.
* - Data Validation Fail: Returns messages for missing @docgroupid, @peoplelistid, or non-existing record in database.
*
*
* **Preconditions:**
