Search Structure Extension thorugh Append Structure but not reflecting the New Field added in the 'Available Field 'Column in Configuration

Hi ,

I have extended the Search Structure thorugh Append Structure but the New Field added is not getting reflected in the Available Field Column in Configuration (Standard as well as custom configuration)

The New Field added is getting reflected in the Context Node but missing in the configurations.

Component Details:

BSP Component: BEADLS_BILLDUE

Dynamic Query Object: DLDynamicSearch

Search Structure: BEAS_DL_DYNQUERY_IL

Please let me know the possible correction required and the root cause of this issue. Thanks in Advance.
