Flink的vvp作业表级别血缘显示有问题，怎么回事？
insert into dws_trans_log_dtl_top_lg_transfer_detail

left join top_acct_transfer b on a.acct_transfer_ord_id = b.ord_id
left join dim_top_acct_transfer FOR SYSTEM_TIME AS OF a.proctime AS dim_b on b.org_ord_id = dim_b.ord_id
left join spin_ssp_prod_usr_indv_base_info FOR SYSTEM_TIME AS OF a.proctime AS usr_indv_base_info on a.in_huifu_id=usr_indv_base_info.huifu_id
where a.transfer_type in ('PAY_CONFIRM','ACCT_PAYMENT','HYC_CFM_TRANS','HYC_ACP_TRANS','LJH_CFM_TRANS','LJH_ACP_TRANS','LJH_FEE_TRANS','LJH_SPLIT_TRANS')
and b.transaction_flag in ('H','L')
本该有4张source table的，只显示了3张，漏了dim_top_acct_transfer表，是不是因为最后写入sink表时没有带上该dim表字段导致的？
