Fix Date Formats with Curly Braces in SAP BEx and Excel 365
Question details
The user needs to fix an issue where the SAP BEx variable dialog in Excel 365 displays curly braces and rejects certain date formats.

- Product
- Microsoft Excel 365, SAP BEx
- Device & OS
- Windows 11
- Scenario
- Entering specific date formats into the SAP BEx variable dialog prompt within Microsoft Excel.
- Observed behavior
- The variable dialog displays curly braces. Date formats such as yyyymmdd and yyyy-mm-dd fail to process correctly, while the yyyy.mm.dd format still works.
Ensure you have administrative privileges on your Windows system, as you may need to adjust regional formatting settings or repair the SAP Analysis for Office installation.
Synchronize Windows Regional Settings with Excel and SAP BEx
Adjusting the Windows regional date and time settings ensures consistency with the SAP BEx add-in and resolves formatting conflicts that cause curly braces to appear.
In many cases, the SAP BEx add-in relies heavily on the operating system's regional configuration. A mismatch between the date format expected by the SAP server and your local Windows settings can result in parsing errors displayed as curly braces.
Press the Windows key, type 'Control Panel' in the search bar, and press Enter to launch the application.
Navigate to 'Clock and Region' and click on 'Region' to open the regional format configuration window.
Under the 'Formats' tab, ensure the 'Short date' format matches the required SAP BEx format (for example, change it to yyyy-MM-dd or yyyy.MM.dd depending on what works in your environment).
Click 'Additional settings...' at the bottom of the window. In the 'Numbers' tab, verify that the 'List separator' is correct for your region (typically a comma or semicolon).
Click 'Apply' and then 'OK'. Restart Microsoft Excel and the SAP BEx add-in for the new formats to take effect.

Repair or Update the SAP Analysis for Office Add-in
If adjusting the regional settings does not work and the curly braces only appear within the BEx dialog, the add-in itself may need to be repaired or updated.
Try WPS Office for Seamless Spreadsheet Management

Frequently Asked Questions
Why does the SAP BEx variable dialog show curly braces?
Curly braces typically indicate a parsing error or a mismatch between the date format expected by the SAP server and the regional settings configured on your local Windows machine.
How do I change the default list separator in Windows 11?
Go to Control Panel > Clock and Region > Region > Additional settings. In the Numbers tab, locate the 'List separator' field, change it to your preferred character (like a comma or semicolon), and click Apply.
Does Excel 365 support the legacy SAP BEx Analyzer?
Support for the legacy SAP BEx Analyzer is limited in newer Excel 365 versions. SAP strongly recommends migrating to 'SAP Analysis for Microsoft Office' for full compatibility and ongoing support.
Can I use SAP Analysis for Office with alternative office suites?
SAP Analysis for Office is specifically designed and compiled as a COM add-in for Microsoft Office. It requires a local installation of Microsoft Excel to function correctly and connect to your SAP server.
