近日，接到项目组同事ABAP开发请求无法保存的情况，询问后得知是一出口程序无法保存，保存时一直报错，按帮助提示如下:
Diagnosis
An operating system file (the SAPNAMES file of user CRCCI003) could not be accessed from the program that is running, since it is locked by another transaction.
The name of the lock file is "/usr/sap/trans/tmp/CRCCI003.LOS".
Procedure
Execute the function again after a few seconds.
If the message occurs regularly, contact your SAP administrator.
将原来的请求release掉，再重新生成新的请求，保存时也出现这问题。问题一定是处在OS上了，找到/usr/sap/trans/tmp目录，果然有一个lock file叫CRCCI003.LOS，是CRCCI003用户产生的锁定文件，将其删除。在删除前先做好该文件的备份，以防万一，备份为CRCCI003.LOS.BK即可，然后放心的删除CRCCI003.LOS，至此问题完美解决，请求可以保存了.
