JCO 连SAP的问题

[Former Member]

一直用JCO连SAP都没问题，昨天突然报如下错误

（103） RFC_ERROR_LOGON_FAILURE : CONNECTION CLOSED WITHOUT MESSAGE (CM_NO_DATA_RECEIVED)

网上查过好像也没有关于这个报错的信息。挺郁闷的，哪位兄弟能帮解释一下这是什么原因？

你可以看看一下的链接：

和下面一些建议

I guess your BAPI (Z....) pops up some dialog when run from R3....

This is not acceptable for the RFC call. You need to supply the parameter up front in the RFC parms.

When called from Java you cannot have any screen interaction. P.S. There may be a parm "run dark" or something like that. It would need to be checked for RFC...

Tell your ABAP programmer to modify the BAPI...

you can look at SM21 or ST22 to see if there's any additional error message or ABAP dump?
