BW Data Type Conversion

Hello everyone,

I have a problem about getting divided of some formulas. I want to divide two formulas which is charactheristics of 0GLACCOUNT and 0MATERIAL_0MATL_TYPE. I'm using NDIV0 data function while I am dividing two formulas on my query however it did not work out.

I'm given the general logic below:

NODIM("[] x" / "[] y") (x and y are different type of data units. How can i convert them or which function should i use to understand hana both x and y have the same types?

Could you help me to solve this problem?

Best regards,
