How to enable custom field on Create Supplier Invoice - Advanced?

[SAPSupport]

In "Custom Fields and Logic" app, I have created a custom field with a business context.
I can add the field through APP Create Supplier Invoice(F0859).

But how could I show the field in APP Create Supplier Invoice - Advanced(MIRO)?

The custom fields maintained for the Fiori app do not have effects on the advanced app because another back-end logic is in use, with respect to the user interface.

For MIRO, you can maintain custom fields on transaction SHD0 or OLMRLIST.
Then, you can manage logic for the custom fields by implementing your custom logic. BAdIs INVOICE_UPDATE and MRM_HEADER_CHECK may help, as well as user exit EXIT_SAPLMRMP_010.

Hi  SAPSupport

Employee,

We have a requirement to extend MIRO to add custom tab in the item details. For that, MRM_ITEM_CUSTFIELDS BADI to be implemented. We are in S4 HANA and we already have Fiori custom fields created for the app.  The ZZ fields are appended in the RSEG table. 

Therefore, instead of creating new fields again (in DRSEG_CI and CI_DRSEG_CUST) is there a way to call the Fiori custom fields already existing in the RSEG table for MIRO in SAP ECC? 

Would be very happy and much appreciated if I get your answer for this OR is there any other way to bring those fields to MIRO?

Hello,
