{% step %}
Start by ingesting your document. If you try to ingest the same document again, you'll encounter an error.

![](/files/7RPWdrLwGgpV0TEoqQnr)
{% endstep %}

{% step %}
Import the same document again.

![](/files/661pXfa3mxhQbUgQGkQF)
{% endstep %}

{% step %}
Note that the Excel sheet you're importing contains the same data.

![](/files/SIxQlRtf5j0J7ONMEUXB)
{% endstep %}

{% step %}
Select the same template and attempt to reinvest the data.

![](/files/rerqUD2HLYWlMty4F16Y)
{% endstep %}

{% step %}
Review the error message that appears.

The error message indicates that invoices in a terminal state can't be modified. This happens when you try to reinvest data for an invoice that's already been generated. The government doesn't allow the same invoice number to be used again, so you'll need to use a different document number.
{% endstep %}

{% step %}
If you're facing this issue, check the document number.

![](/files/0iNm0v3Rvs2rjmb0Mwf2)

Copy the document number, close it out, and go to the filters.

![](/files/QI9XHVXcvjYEYK0zheV1)

![](/files/wcVcR4zKeWvOTXMo24YL)
{% endstep %}

{% step %}
Apply the document number in the filters.

![](/files/Pb2LO2LFzxkfpFgmqYN2)
{% endstep %}
{% endstepper %}

This way, you can check if the document was already generated and update your team accordingly.
