When creating a standard invoice one of the following errors appear under a specific line item:

The subtotal under this line exceeds limit.

or

The serviced amount under this line exceeds limit.

The Purchase Order (PO) Commerce Extensible Markup Language (cXML) file, contains a value, lower than the supplier is trying to invoice on a line item.

The tag <MaxAmount> needs to be set with a valid value. To check this information:

1. Check the <MaxAmount> tag in the PO cXML file.
   This tag specifies the maximum amount the supplier is allowed to invoice for each line item.
2. Validate the invoice values.
   

   Confirm whether:

   • The invoice line amount exceeds the value in the <MaxAmount> tag, or

   • The unit price being invoiced is higher than the <MaxAmount> value.

3. Contact the buyer for correction.
   If the <MaxAmount> value is incorrect or too low, request the buyer to update this field in their backend system.

4. Resend the updated PO.
   After the buyer makes the correction, the PO must be resent to the supplier so they can submit the invoice again without errors.

Note: When the supplier is trying to invoice, the value 0 will always be invalid:

<MaxAmount>
<Money currency="USD">0.00</Money>
</MaxAmount>

If this solution doesn't resolve the error, proceed with the same described steps above to the tags ExpectedUnplanned and MaximumUnplanned in the PO cXML file:

<Extrinsic name="MaximumUnplanned">
<Money currency="USD">0.00</Money>
</Extrinsic>
<Extrinsic name="ExpectedUnplanned">
<Money currency="USD">0.00</Money>
</Extrinsic>

Note: these tags can have their values updated to a valid one or be removed.

The tags mentioned in the article are added by the ERP or P2P systems, which means that it comes from outside of SAP Business Network.
