Resource not found for the segment 'to_MaterialGroup

[Edson]

Hello experts.

They reported an error to us when using a fiori app, which, apparently, is a custom app, an extension of a standard app, this being the Manage Billing Documents app (App ID F0797), where when entering to review the Item, the window marks the next error.

And when checking the console, the following error appears.

"Resource not found for the segment 'to_MaterialGroup'.

Reviewing the SAP GUI, in the transaction /IWFND/ERROR_LOG it describes the error on the Odata SD_CUSTOMER_INVOICES_MANAGE, but reviewing it, it is marking everything correctly, the metadata, the files, and everything comes out with a 200.

We reviewed some notes that talk about the topic, but none of them helped us, we cleared cache, we reviewed reloading the metadata and everything that one of the notes explained.

2743849 - Recurso no encontrado para el segmento 'XXXXXXXX' - SAP for Me

Any ideas what we could check? Something that perhaps we are overlooking and therefore, we have not found the solution?

I will appreciate all the answers that you kindly share with us.

Greetings.

EBZ.
