I wrote a simple script to aid users moving to a new password policy, users were put on a policy which would expire a password after a day. Once they had changed their password the policy is amended to the new policy. I now use this for forcing password resets. Replace and with your Sage Line 500/1000 password policies

-- =============================================
-- Author:           Christopher Smith
-- Create date: 18/07/2018
-- Description:      Implement the new password policy in stages.
-- 1. Change the password policy first to enforce a password change in a short time period
-- 2. Backup and truncate the table [csmaster].[scheme].[pwdhistm]
-- 3. Run this routine nightly, it will pickup users who have changed their password and set the new policy

Below is the code used to force users to enter a new password upon login

USE [csmaster]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE procedure [dbo].[usp_ForceSagePWChange] @user char(8)
--EXEC usp_ForceSagePWChange ''
AS
--IF @user = 'ALL' GOTO ALLUSERS
--IF @user != 'ALL' GOTO SINGLEUSER
BEGIN
/*ALLUSERS:
update scheme.passexpm
set setup = '10001'
GOTO FINISH
SINGLEUSER:*/

update csmaster.scheme.passexpm
set setup = '10001'
where user_id = @user
update csmaster.[scheme].[usermastm]
set [sec_group] = ''
where name = @user
GOTO FINISH
FINISH:
END

I have found users don’t always read the logs from the Adaptus EDI Module anymore in Sage Line 500.
There are a few reasons why orders get stuck, the most common is a customer has sent a duplicate EDI file although one was caused by incorrect product supersession setup causing an endless loop.

-- Create date: 01/08/2017
-- Description:	The procedure looks for orders held in the EDI IN Intermediary Tables
-- Changes:
-- 1.0.1 - 02/08/2017 - Added dateformat dmy as when run was reporting "Conversion failed when converting date and/or time from character string.".  Ensured all date values were cast as datetime as well.
-- 1.0.2 - 11/04/2019 - Corrected the Sales Order lookup to check the invoice customer instead of delivery customer on opheadm
