CAP Fiori Elements Excel Export columns from different entities

[Andreas05]

Hi,

we are currently facing an issue with excel export in a CAP (V4) based FE app.
1. We have an object page with following table:

Excel Export is activated by default and creates following file:

The currency is missing in the excel sheet although it is displayed in the table on the OP.

Here is the schema.cds file where amount and currency are set to be displayed together:

Amount and currency are coming from different entities (LossDocumentItems and LossDocuments).
It seems that it is not possible to show values from different entities in the excel export although you can display them together in the table.

The currency is only displayed in the excel sheet, if I add the currency field to the entity LossDocumentItems.

Is this a bug or a desired behavior.

Could you please help?

Kind regards,

Andreas
