AET in dependent Object

Hi Experts,

  I am having a requirement where i need to add 5 fields in the table BUT0ID, which is a business partner Identification table. I need to add the same 5fields in corresponding structure CRMT_BUPA_IL_IDENTIFICATION. So that i can able to use those fields in webui and i can save the values in BUT0ID table. How i will achieve this? Need your help.

Note :

1. BUILIDNUMBER is the dependent object.

2. Component : BP_DATA/Account ID number list , Context node : Builidnumber

3. structure CRMT_BUPA_IL_IDENTIFICATION has enhanced 'category as cannot be enhanced' not able to add append structure.

Thanks,

Arun
