[Love2Explore]

Hello Everyone,

If this is not correct channel please let me know where I can post this ?

I have one Hana Native Calculation view inside db/src folder which is exposed to CAP by CDS entity like below.

On top of this CDS entity I have created a CAP service with input parameter like this.

While opening Calculation view in HANA explore with parameter , it provide some results.

But when I am running service with same parameter value it doesn't provide me any value.

Could someone help here , What i am doing wrong?
