Add Document Reference Num. to KSA E-Invoice Form - Public Cloud

[Mahmoud-Farag]

Dears,

I have requirements to add 'Reference Document Number' to E-Document KSA, We are on Public Cloud and the field found in the XML of the Invoice.
So we have to download the Form and try to update it using adobe life cycle, but we did not find the field for Ref. Doc. in the data source of the form ''FDP_EDOC_KSA_XML_FORM_SRV''

SAP recommended to try the extending the Form Data source so we have checked 'Custom fields' App and try to
extend the Data source of the EDOC but we did not find any data source related be extend.
Have anyone Advice for me or ant recommend.

Thanks,
