Transport Errors after upgrade to BI 7.31

Hi Everyone,

Problem with Transport of transformation from Flatfile datasource to DSO

Recently we upgraded our system from BW 7.0 to 7.31.

We are facing issue with transport.

When we attach the transformation from flat file data source to an infoproviders to a TO and do transport , it gives RC12 and the import queue is blocked.

Rest of the transports containing transformation between two infoproviders are transported successfully.

But the problem occurs with transport of transformation between datasource and infoprovider

Any ideas or thoughts in this regard ?
