1. 检查SAP日志文件的位置，并确保路径中没有任何空格。
2. 检查系统的日志文件大小，确保日志文件不超过限制大小。
3. 检查日志文件是否被彻底清空，如果日志文件被删除或清空，请重新创建日志文件。
4. 检查SAP服务器硬件设置，确保服务器设置正确。
5. 手动查询SAP数据库中的日志文件，确保日志文件存在并可被访问。
干了坏事要消除罪证？你要把audit log 和 system log 都删掉才行 audit log 删除1. To access the Security Audit Log reorganization tool from the SAP standard menu,choose Tools à Administration à Monitor à Security Audit Log à Reorganization.The Security Audit: Delete Old Audit Logs screen appears.2. Enter the Minimum age of files to delete (default = 30 days).This value must be 3.3. Activate the To all active instances indicator to delete the audit files from all applicationservers. Leave the indicator blank if you only want to delete the files from the localapplication server.4. Activate the Simulation only indicator if you do not actually want to delete the files. In thiscase, the action is only simulated.5. Choose Audit Log à Continue. 但这个只能删3天前的，如果你一定要删现在的需要操作系统的权限 （操作系统下做动作的话，操作系统也会有日志的，各系统设置不同，请自行脑补） audit log 在参数 rsau/local/file 里决定路径和文件名。system log system log 分本地log 和全局log 都要删If the syslog really should be deleted, you should first consider, that for 'n' application servers, there are 'n' syslogs, plus 1 central syslog. (The central syslog only exists if at least one machine is running UNIX.)You need the filenames. These can be determined, for example, with the report RSPFPAR or the command 'sapparar'. The following table shows the profile variables and typical values:rslg/central/file /usr/sap/C11/SYS/global/SLOGJrslg/central/old_file /usr/sap/C11/SYS/global/SLOGJOrslg/local/file /usr/sap/C11/D01/log/SLOG01rslg/send_daemon/status_file /usr/sap/C11/D01/data/rslgsstaR/3 must be stopped. If the operating system was not also restarted, the shared memory segment 'SCSA' may still exist. This must also be removed. Possible ways to do this are listed in note number 12715.To delete the central syslog, both syslog files must be deleted. They are recreated automatically when the system is restarted.To delete one of the local syslog, stop the corresponding application server and delete its SCSA. The syslog file and the small management file are then deleted. They are recreated automatically when the system is restarted.If the locale syslog file is mistakenly deleted without the described preparation, it is recreated incorrectly. However, it can be repaired after this with the report 'RSLG0020' (note 21153).翻滚吧，骚年
系统会反馈消息，消息分为三个等级，正确/警告/错误。消息提示会明细到某个物料或组件。依次处理即可。
需要注意的是，系统仅能反馈逻辑性错误（即有无材料价格，有无作业费率）。当缺少BOM组件或工艺路线以及数量不准确时，系统无法反馈。
如果有错误，AJRW会提示，如果AJRW没有提示错误，正式做就可以。
有错可能是有不完全的资产、折旧没提完等等，看AJRW的提示。
