Track Supplier Invoice app, for cost center PO only?

Hi guys,

I just got access to a S4HANA installation and trying out some MM process.

I notice that the Track Supplier Invoice app does not list any invoices that is not raised with Account Assignment. Is that the way its supposed to work?

If it can also track standard stock po, what can I do to list both PO with account assignment and non?

Below are the steps I maintained to get data into the app as initially it started with error messages  requesting to maintain the personalization.

App Implementation: Track Supplier Invoices - SAP Fiori for the SAP Simple Finance Add-On 1.0 - SAP Library

Define Cost Centers and Cost Center Groups

This app displays only supplier invoices for company codes whose cost centers have been defined. If you have not defined cost centers for any company codes, an error message appears to prompt you to do so when you launch the app. To define the cost centers and cost center groups for the company codes, complete the following steps:

1. Run transaction FPB_MAINTAIN_PERS_S.
2. Enter DIA_CCC in the Personalization Dialog field and then choose the Execute (F8) pushbutton.
3. Fill out the required fields.
4. Save your entries.

Thanks for the help.
