今天在测试开发的一个流程时，当走到一步叫做“Patent Director of Engineering Approval”的步骤，死活报错：“String or binary data would be truncated”，按照这个错误提示，通常来讲这个错误是数据库的表字段长度太短，而添加到此字段的字符长度超过本身定义的长度而造成的。经过不停的调试修改当前步骤涉及到的字段，始终不得解决，反而还造成了流程进入到一个“空白区”，卡在了2个步骤中间，后来只能通过后台修改表BPMInstProcSteps的FinishAt为Null，为避免此问题再次发生，在咨询官方技术人员后，还修改了服务器上的server.config中DTC的设定，开启了事务支持。
附上手工修正的SQL语句：
Update [BPMDB].[dbo].[BPMInstProcSteps] Set FinishAt=Null Where StepID=26403
第一个要分享的是获取当前的申请状态以及当前的处理人，虽然我们很容易通过BPMInstProcSteps这张表找到FinishAt is Null的记录，但是如果直接用2表的关联查询会有并行流程的问题，另外当你把自己的申请数据独立开来，做跨数据的关联就有些不直观，索性写一个函数GetBPMCurrentStep(@TaskID)，使用方法很简单，直接在自己的视图里面使用就行。
USE [WAIWorkflow]
GO
/****** Object: UserDefinedFunction [dbo].[GetBPMCurrentStep] Script Date: 05/24/2011 14:34:50 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[GetBPMCurrentStep](@TaskID nvarchar(50))
RETURNS nvarchar(Max)
AS
BEGIN
DECLARE @r nvarchar(Max)
SET @r = ''
SELECT @r = @r + ',' + NodeName + '('+ OwnerAccount+')'
FROM [BPMDB].[dbo].[BPMInstProcSteps]
WHERE TaskID=@TaskID
AND [FinishAt] is null
RETURN STUFF(@r, 1, 1, '')
END
1、AD集成方面一定要注意IIS里面的Directory Security的验证方式要选择“Integrated Windows Authentication”。同时，Flowportal安装目录下的Server.config要修改如下：如果要取消网页认证的话，把WebLoginEnable修改成False即可。
