当我使用带有ISIN或CUSIP的bdp时,我得到以下错误.
bdp ("US25470XAB10 ISIN","ULT_PARENT_TICKER_EXCHANGE")
bdp ("25470XAB1 CUSIP","ULT_PARENT_TICKER_EXCHANGE")
Error in bdp_Impl(con, securities, fields, options, overrides, identity) :
attempt to set an attribute on NULL
但是,使用Bloomberg ID(下面)似乎可行.
bdp("EI000902 Corp","ULT_PARENT_TICKER_EXCHANGE")
欣赏任何变通方法或解决方案.
