Common Accounts Payable (AP) checks​

Invoice face value discrepancy​

{
  "checks": [
    {
      "rule": "{amount_total} == {amount_total_base} + {amount_total_tax}",
      "type": "error",
      "message": "Total amount is not equal to the sum of amount base and the tax",
      "automation_blocker": true
    }
  ]
}

Sum of line items must match invoice total​

{
  "checks": [
    {
      "rule": "sum({item_amount_total}) == {amount_total}",
      "type": "error",
      "message": "The sum of line items is not equal to the total amount.",
      "automation_blocker": true
    }
  ]
}

At least one field must be filled​

The following Business Rules Validation configuration shows errors only when all the values are empty. It is satisfied if at least one of the values is filled.

{
  "checks": [
    {
      "or": [
        {
          "rule": "has_value({aaa})",
          "message": "At least one value has to be filled."
        },
        {
          "rule": "has_value({bbb})",
          "message": "At least one value has to be filled."
        },
        {
          "rule": "has_value({ccc})",
          "message": "At least one value has to be filled."
        }
      ]
    }
  ]
}
