Date Conversion of Persian in whole Landascape?

[workgit]

Hi,

I am Working on S/4HANA OP 1809 & 1909 & 2020.

We have some Users that use Iranian Calendar and they Change their DateFormat to (C) in SU3.

This works fine in Fiori and SAPGUI for Inputting Data, But when data is sent to Backend (by oData || SICF) the Date is not in Georgian. It still is in Iranian (eg:13990823- it should be 20201113).

I hope you understood the issue.

I put some Enhancements for Odata Calls on Class /IWBEP/CL_MGW_REMOTE_HANDLER >- Method: DESERIALIZE_REQUEST.
But if data comes as binary(I Convert XString to String), There is a Risky work to find the date (using Persian Date Regex -8 digit - first 1 - second 3 or 4) and Convert it. Maybe the Input is an Amount with the same Pattern.

Is there a Core Point to Convert all Dates??!
or Some Profile Parameter to tell System Sends data with Georgian and not User Calendar.

Any help would be appreciated .

Thanks in advance.

Regards.

Do you have this issue with SAP standard applications or just with your own applications / services?

Dear @Gregor, this happens on all apps. SAP GUI and Fiori Apps
