Approve Travel Expense issue

Hi Team,

I enhanced the BAdi "SRA008_BADI_APV_TRAVEL_EXP" for Approve Travel Expense Fiori App.

Steps Followed:

1) Added Fields in the Structure.

2) Populated values for the new fields

3) I am able to see the newly added  fields and the values for these fields in the back end debugger.All the newly added fields and data is finally retrieving to "er_entityset" .

4) cleared the cache in both front end and back end.

Issue:

1) I could not able to see the newly added fields in the metadata.

2) we don't have any other BAdi to enhance the model.

Please provide some inputs?

Thanks

Vijay
