Adapter Log File Error Messages
The log file for the Adapter for SAP displays the following message just as the adapter is starting:
SAPAdapter.SAP-ESISAPAdapterConfiguration Error [Application] AER3-000183
RFC error; Group : 104, Key : User is locked. Please notify the person responsible, Message : User is locked. Please notify the person responsible.
The adapter appears as if the start-up was successful. The following success message appears in the adapter log:
SAPAdapter.SAP-ESISAPAdapterConfiguration Info [Adapter] AER3-000082
Successful initialization of Adapter 
However, when Windchill ESI issues a call to the adapter, the following error message appears in the adapter log file:
SAPAdapter.SAP-ESISAPAdapterConfiguration Error [Application] AER3-000072
Client connection SAP-ESISAPAdapterConfiguration InboundConnection0Client0 is
invalid 
In addition, the following text appears in the dev_rfc.trc file:
T:1256 ======> User is locked. Please notify the person
responsible
T:1256 <* RfcReceive [1] : returns 3:RFC_SYS_EXCEPTION
T:1256 <* RfcReceive [4] : returns 3:RFC_SYS_EXCEPTION
T:1256 RfcGetAttributes: Invalid handle [3]
This happens when the SAP user name and password have become locked.
To resolve this issue an SAP administrator would have to unlock the account and you would need to verify the user name and password that is specified in the adapter configuration. For more information, see the Windchill Enterprise Systems Integration Installation and Configuration Guide - SAP.
