AET error while creating a new field

Hi Experts,

We have a requirement to create a check box/newfield on Account Details screen in Web UI. I am trying to create a new field using AET but am getting the following error message. Please help.

1. Error during generation of object CI_EEW_BUT000

2. Customizable CSOL conflict for objects changed in other TR.

We have a config TR involving the role field on account details component (BP_HEAD/ACCOUNTDETAILS). Do we need to release the transport before creating any new fields.

The generation of the field fails when I select the extension and click on 'SAVE and GENERATE'.

Please help.

Thanks,

Rohit
