Error occured while inserting record: Operation against file 'sn_install_base_m2m_contract_sold_prod

Hi,

I'm trying to insert a record via subflow, but getting error as "Error occured while inserting record: Operation against file 'sn_install_base_m2m_contract_sold_product' was aborted by Business Rule 'Account Check^b8d424091bf0de10368e848cd34bcb5e'. Business Rule Stack:Account Check". What must be the issue here.

Note: I can't inactive the BR.
