Problem of Calculation View based on SQLScript

Hi All,

I am facing a strange problem in SAP HANA Studio, when I create Calculation View based on SQLScript, not graphical, when I deploy and activate it works properly for few times till I update it and redeploy it, and then try to reopen it gives error "Repository Error" and does not open again. this is always the behavior not in some cases.

can you help me how to fix this problem?
