比来须要用ABAP触发处理惩罚链，并且还要把握处理惩罚链的履行次数，找了很多材料，终于成功实现了。我目
前知道的办法有两种。一种是直接经由过程SAP供给的API函数去触发处理惩罚链，别的一种就是经由过程事务触发处
理链。下面分别对两种触发处理惩罚链的办法做大致申明。
Method1：API
在BW中，找到Function group : RSPC_API
里面有如下函数：RSPC_API_CHAIN_GET_ERRORS
RSPC_API_CHAIN_GET_LOG
RSPC_API_CHAIN_GET_PROCESSES
RSPC_API_CHAIN_GET_RUNS
RSPC_API_CHAIN_GET_STARTCOND
RSPC_API_CHAIN_GET_STATUS
RSPC_API_CHAIN_GET_VARIABLES
RSPC_API_CHAIN_INTERRUPT
RSPC_API_CHAIN_MAINTAIN
RSPC_API_CHAIN_RESTART
RSPC_API_CHAIN_SCHEDULE
RSPC_API_CHAIN_SET_STARTCOND
RSPC_API_CHAIN_START
RSPC_API_GET_CHAINS
RSPC_API_PROCESS_GET_INFO
RSPC_API_PROCESS_GET_JOBS
RSPC_API_PROCESS_GET_LOG
RSPC_API_PROCESS_RESTART
RSPC_API_SYSTEM_MESSAGE_GET
信赖大师经由过程函数名称也可能知道了函数的功能。放一个PDF介绍这些函数的，有爱好的可以研究一下。

这里我应用RSPC_API_CHAIN_START来触发处理惩罚链，这些函数都是RFC函数。
当然，要想多次履行处理惩罚链，必须包管前次的处理惩罚链履行已经停止。所以如何获取处理惩罚链的状况，也是个题目。
我还是应用这里面的函数RSPC_API_CHAIN_GET_STATUS来获得处理惩罚链的当前状况。以此断定处理惩罚链是否履行完成。
下面是示例法度代码：
REPORT ztest888 MESSAGE-ID ZXXX.
DATA: logid TYPE rspc_logid.

ELSE.

MESSAGE e000 WITH ""PROCESS CHAIN"" p_chain ""START UNSUCESSFUL-"" sy-index.
"ADD 1 TO TIMES
times = times + 1.
ENDIF.
ENDDO.
METHOD2：经由过程定义事务触发处理惩罚链。
这种办法在Software Developer Network上已经有教材了。这里上传一PDF文档，只须要按照此文档操纵，就不会有题目了。
但这种访求须要将处理惩罚链开端变式设置为：直接规划->事务后->输入事务和参数。事务用事务码SM62定义。
并且调剂功课 。PDF文件下载地址：/Files/clsoho/TriggeringtheProcessChainsatParticularDateusingEvents.pdf

这两种办法的差别在于一个是直接经由过程API函数去触发处理惩罚链的，须要将处理惩罚链开端变式设置为应用元链或API。然则第二种办法是经由过程
事务触发处理惩罚链的，所以须要将开端变式设置为直接规划，事务后输入事务和事务参数。并且须要调剂处理惩罚链后，履行法度才干触发。
当然，代码不是很完美，有可能会产存亡轮回等题目。可以按照须要自行批改。BW处理惩罚链完全可能进行集成，以削减IT人员的保护压力。
今后我会连气儿存眷这些题目。
