Fiori extend apps - performance optimization

Hi,

We extended standard SAP Fiori apps added new "Entity Types" and "Entity Set" through SEGW.

Refined /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_EXPANDED_ENTITY method added below code.

implemented BADI SRA020_PO_TRACKING and add logic to fill content in new EntitySet.

Normal URL:

/sap/opu/odata/sap/ZFIORI_MM_SRA020_ODATA_SRV;mo/PODetailedDatas(SAP__Origin='ECCCLNT110',PONumber='XXXXXXXXX')?$expand=POItems

Extended URL:

/sap/opu/odata/sap/ZFIORI_MM_SRA020_ODATA_SRV;mo/PODetailedDatas(SAP__Origin='ECCCLNT110',PONumber='XXXXXXXXX')?$expand=POItems%2cZZAttachments

Both URLs are working fine.

My query, In WEB IDE UI5 developers created a extend project and mapped the extend content(ZZAttachments) to UI. Business functionality wise application is working fine.

But I find a additional call in 'Network' tab in 'inspect element' through Chrome. How to avoid the 1st call.

Thanks,

Lakshman Balanagu.
