AET Field Value is not being saved at first time and second time onward it's saving on the database

Hi Gurus,

I have created couple of AET fields and pulled on service request (SR) overview page. The object type is selected as CUSTOMER_H. when I create new SR, provide values on AET fields and save - transaction is saved but the AET field values are not saved.

When I edit the same transaction again and fill the AET field value and save-  transaction is saved with AET field values .

While debugging in setter method I found that the relationship 'BTHeaderCustExt' doesnot exist for the first time and second time onwards its showing the relationship. Due to which 'Current' is empty in line no 28 and hence not able to save values.

\

Has any one faced similar issue earlier and what's the way to resolved the issue?

Thanks,

Anand
