Unsupported Functions and Formulas for Calc on the Fly

Certain functions and member formulas are not supported for performing calc on the fly.

They are as follows:

Members having assignments to themselves or other members are not allowed in member formulas. For example,
```
sales = 100 + units *rates;
```
Only single value formulas are allowed.
Multi-statement formulas are not allowed. For example,
Allowed:
```
if(sales > 100) 10;
 units * 1.01;
else
units + 10;
endif;
```
Not Allowed:
```
If (units > 10)
 10;
endif;
units + 10;
```
Functions that require more than 50,000 off sheet cells are not supported.
Recursive formulas and circular references, where a formula refers to its own cell directly or indirectly, are not allowed.
The following list of Essbase calculation functions are not supported for calc on the fly:
- @TODATE
- @ISRANGENONEMPTY
- @MDANCESTVAL
- @MDPARENTVAL
- @RETURN
- @SANCESTVAL
- @SHARE"
- @SPARENTVAL
- @XREF
- @XWRITE
For ASO cubes, only outline math is interpreted while inserting member formulas. MDX formulas are not supported.
