cannot create init load

Hi all,

I intended to loaded data from ODS into the Cube. I already created the 'full load' to test the data.

Now I want to created the 'init load' and 'delta load' infopackages; then use 'delta load' one to run the process chain.

<b>Question: I cannot create the 'init load'; there is an error message: datasource xxxx cannot be updated into an ODS object.</b> Is it because I didn't chose the 'initialize without data transfer' under the 'initialize delta process? Does it matter that there are many infopackages under this infosource( don't think so)? Can someone point out the problem and solution? Thank you very much.
