Hello,

I have this particular window made of a view defined on a utility package (that is the only view defined there).
 

 
As per the experiments that I’ve done (till a while ago) and as per expert advice on the domain, out goes it candidacy to entertain custom fields, but I have circumvented the difficulties somewhat (if I believe correctly) and come up with the following:
 

 
That is to say that, I have defined three custom attributes C_COMPANY, C_SERIES_ID and C_PAYMENT_ID as referenced values, such as →

PaymentTransaction(Item_Trans_Id).Company

and used it on a fourth custom attribute -

Payment_API.Get_Pay_Date(Pay_Trace_Util_Cfp.Get_CF$_C_Company(v.objkey), Pay_Trace_Util_Cfp.Get_CF$_C_Series_Id(v.objkey), Pay_Trace_Util_Cfp.Get_CF$_C_Payment_Id(v.objkey))

with expression as custom field implementation type.

Although all goes well until after publishing, I can’t add this to the window aforementioned.

Am I stuck at a dead end or is there something more to do to achieve my end?

Please comment on the advisability of my method.
