BP Industry Code using BOL relationship.

Hi Experts

I am trying the get the BP Industry Code using BOL relationship.

I can see  attribute from the Genil_model_browser with given path

@BuilHeader=>BuilIndustrySectorRel@BuilIndustrySector >INDUSTRYSECTOR(field)

I took a BP number from BP transaction which has INDUSTRYSECTOR. When tried to see the INDUSTRYSECTOR field value from the genil_bol_browser.

BuilIndustrySectorRel is does not show any further navigation.

I know how to get the INDUSTRYSECTOR using FM(crm_bupa_frg0040_get_detail). But usage of FM in UI fields Get method become performance issue.

Can you please give me some pointer to get the INDUSTRYSECTOR to retrieve using BOL code.

Thanks
