Skip particular codeunit during import from worksheet.

Hi everyone,

I want to skip one codeunit during import. But After reading the file, when I select skip in worksheet, its store 100% but after that during processing its not skipping that particular codeunit, its showing the error[Same like, During the comilation of this paticular codeunit].
(Error is: There is not enough memory to complete the current activity.)
Please tell me ,how can I skip that particular Codeunit during import or any suggestion.

thanks,
Mani.
