SAP Business One messages can be created using DI API. These messages are displayed in the Incoming Messages area in Business One.

The basic query to prepare to send a message will be something like this.

select
t0.UserID, t0.User_Code, t0.U_Name, 'Test Message' as "Subject", 'Test message text' as "MessageText", 1 as "SendInternal", -1 as "RecipientTypee", 1 as "MsgPriority", E_Mail
from OUSR t0
where t0.UserID = 1

In this case, the message will go to the “manager” user (UserId 1).

The mapping for the message has two components: the message and the recipients. The mapping will look like the following images.
