Problem with checkin activity

Hi All,

I have problem with Checkin and CheckOut activities while I am trying to work with BAPI's.

I have an iView that is deployed on the portal server. Initially when I am trying to make changes in the iView, they were getting effected in the server. But, once I had created a model and started using BAPI's I could not CheckIn properly and activate. So, the changes are not getting effected. It is asking for "ACTIVATE WITH ALL PREDECESSORS" and even when I asked to do so, the changes are not getting effected. Also, I have tried it many a times and still all the previous checkin activities are persisting and I couldnt workout with the changes.

Anyone would please check the problem and give me a solution.

Regards,

Murthy.
