Transformation file (.xlsx) not available for selection

Hello Experts,

We are working on BPC 7.5 M, Currently our Dimension files, Reports,Input templates,transformation files,Conversion files are in Office 2003 format (.xls and .xlt), we would like to convert them in Office 2007 format (.xlsx/m and .xltx/m).

I have changed the MEMBERSHEET_VERSION from '2003' to '2007 in tbldefaults table and also added [ALL] in DEFAULT_EXTENSIONS and ALLOW_EXTENSIONS properties under Appset parameters in BPC Admin module.

After this I processed all the dimensions and they got created in .xlsx (Office 2007 format).

I am seeing in issue while opening the transformation/conversion file,the issue is that when I try to open the Transformation file I see only ".xls" file type available to be opened, please find the screenshot below.

Do I need to add/modify any property to have .xlsx format to be visible while opening transformation/conversion file.

Please Advice.

Thanks & Regards,

Rohit
