ABAP Class

The ZCL_BICS_CONS_WEBITEM_ABAP class implements the IF_BICS_CONS_WEBITEM_CUST_EXIT interface.

The properties are read in the IF_BICS_CONS_WEBITEM_CUST_EXIT~INITIALIZE ABAP method and stored as a string in the p_properties ABAP attribute as an HTML table.

A hard-coded string is concatenated with the HTML table of the properties and returned in the IF_BICS_CONS_WEBITEM_CUST_EXIT~EXECUTE ABAP method.

The Java-based BEx Web runtime inserts the returned HTML content into the Web template.
