UDA function in essbase not working in Calc Manager

Summary:

Hi team,

We have got Calc Manager enabled through an SR. For the data forms, we need to fetch closing balance of current period as opening balance of next year. Since, there is no Out of box movement dimension to use, we assigned UDA to a custom movement member & was trying to write rule using @UDA essbase function. However, while writing the custom rule, it is not allowing @UDA function or @ISUDA function to deploy.

What is the possible solution available.
