Purchase Order Item is not matched to Invoice Item in Central Invoice Management

[Niklas_Bies151]

Dear all,

i understand from note 3540020 that it is possible to match a invoice against a purchase order in Central Invoice Management (even if there is no PO number on the invoice), if the description, quantity, unit price & currency matches. However when i tried it out the system does not select a purchase order but tries to book it without a PO assignment. 

Here is the purchase order line item:

And here is the invoice:

I have activated the enhanced invocie item matching:

But the system still does not assign the Purchas Order to the Invoice.

Does anyone have any ideas as to why this might be?

Thanks and best regards

Niklas

Hello , you can use option for verification bachground for cim and after on S4HC you should configure a job invoice verification background

Dear Niklas, 

the prerequisite for line item matching is that there is a PO reference on the invoice and it got recognized by OCR. The mentioned note (3540020) is not stating anything else, so it's a misunderstanding that matching can happen without the prior identification of at least one PO reference on the invoice. The matching then tries to determine the best matching candidates out of all line items of the referenced PO(s) based on unit price, description and quantity. I hope this explanation clarifies why your example did not work. 

Best regards

Linda

Hi Linda,

Even i am unable to get correct result for 3 way match.

In my case PO Qty-100, GR Qty - 100, Invoice Qty - 250, hence you would expect 3- way match error.

However as the scorecard explanation given in the note 3540020 , this is not a 3-way match failure !!!

As, Item description is matching and unit price and currency is matching, which gives 0.5 + 0.35 = 0.85, which exceeds the likeness score of 0.65. Hence, invoice is getting processed automatically.

I believe there should be an ability to re-assign matching score. Item description should have score of 0.25 in my opinion, remaining 0.30 for Qty , 0.30 for unit price , 0.15 for currency.

Regards,

Ashish Shah

Hi,

I'm having the same problem as Niklas.

I've already verified that I'm using the same description, quantity, price, and unit price from my PO. The upload works just fine—it recognizes all the data, including my PO number.

However, the invoice created in CIM still doesn't have the PO item assigned, even though the 3-way match seems practically correct.

Does anyone know of any other possible causes for this issue, aside from the LikenessScore?

Thank you for your help.

Kind regards,

Hi Linda, I'm facing the same problem as Nicolas and Ashish, I have 3-way matching active. I’m uploading the Invoice manually, my invoice has PO reference. When I go to Manage Document Information Extraction Templates, Documents and when displaying the Extraction Results of my invoice, I can see 80-100% match (green) for all my line items for the field PO number (83% confidence, actually). Nevertheless, the invoice has no reference object. Moreover, it worked properly on 7.07.2025 and now, all the examples are wrong, even when taking the same invoices for which it worked earlier. Please check it and let us know. Actually it is not possible to test the scenarios with POs at all. Kind regards, Karolina

Hello Linda, are there plans to expand the matching of purchase order items and invoice items to include data fields such as the Global Trade Item Number (GTIN) and/or the supplier material number? These two values appear on our suppliers' invoices and are much more suitable as matching objects than quantities, prices, and short descriptions, which in some cases may even be identical across multiple invoice items.
