Number field in HANA DB (decimal 15.2 or Integer) used as a Measure is (automatically) converted to string

Hi colleagues,

I'm experiencing some problems related to modeling AV:

1. In HANA DB table I have a few values (decimal) fields that I'm going to use in my Analytical View (AV) - > SHINE model, table SO.Item - >fields GROSSAMOUNT, NETAMOUNT,...
2. I'm using them in my AV
3. At the time of creation of AV, I define them as "measures"
4. After I validate&activate the AV I want to test it (of course)
5. I open the data preview for my view and all measures are of type "STRING"

see the pictures attached.

Do you have any idea what's wrong? Lang/locale? Other?

My HANA Studio version is 2.1.4

HANA db version is rev97

thank you & regards,

Blaž
