Port 'A000000001 ' of type 'ALE ' does not exist

We recently moved BI connection from one ERP client to other ( 240 --> 230)

Since there were no objects created in BI system moving was easy. But We are getting the following error when I tried to CHECK. This CHECK is for the BI system itself( RSA1 --> Source Systems --> BI --> Name of the Logical system). Check to the Source System is OK.

Message ID No

Port 'A000000001 ' of type 'ALE ' does not exist EA 571

I checked in WE21, Entry for "A000000001" does not exist.

I also installed Business content BI_CONT and brought up to a level 9.

I am not sure the error is due to installing BI_CONT or moving the source.
