Use Operands + or * for calculation

[sathish_kumar92]

Dear Experts,

I have few mathematical operands stored in SAP custom fields. How do i use it for calculation?

Please take this as example.

ztest-field1 = '100'.

ztest-field2 = '*'.

ztest-field3 = N+n

Now my requirement is i need to pass numeric values to N & n. Since we have addition operand in between them values of N & n needs to be summed & then i need to have formula like below.

Ztotal = ztest-field1 ztest-field2 ztest-field3. (Here ztest-field2 will again be a mathematical operand * ). So that I will get total of field1 & field2.

Thanks & Regards,

Hi Satish ,

If you want to perform Mathematical Operations to your fields declare them with integer characteristics.

data : num1 type int1,

         num2 type int2,

         result type int4.

result  = num1 + num2.

write : result.

Thanks & Regards

Hi Pavan,

My case is field value itself an operand  which may be + or *. How will i calculate in this case.

Hope u understand. field1 will have value 100, field2 will value +, field3 will have value 200.

Now i need to get the total of field1 & field3 by using operand in field2.

Thanks

Hi Sathish,

You may want to use the eval() function in Javascript, in ABAP the Javascript processor is wrapped in class is CL_JAVA_SCRIPT

Check out this useful link for an example.

Hope it helps! Cheers!

Hi Sathish,

Where exactly are you stuck? If I understand you correctly, you have the operands and operators stored in a database table and you need to perform calculations based on them. That should be doable using IF/CASE statements.

Hello satish,

you can simply use CASE statement and get your result.

For example : -

Case ztest-field2.

when '*'.

ztotal = (ztest-field1) * (ztest-field3).

when '+'.

ztotal = (ztest-field1) + (ztest-field3).

when others.

endcase.

You can have a maximum of 4 operations

So...

CASE Field2. " [OPERATOR]

When '+'.

Result = field1 + Field3.

When '-'.

Result = field1 - Field3.

When '*'.

Result = field1 * Field3.

When '/'.

Result = field1 / Field3.

Endcase.

Hi,

Read the first field contents in 3 different variables and a CASE.. ENDCASE to select the operation as per the operand( Its few in numbers). For the 3rd field is the format always like N+n, N*n, N-n.. Then i guess this can be read by offset and processed.

Can you also clarify the datatypes of the fields and the context.

Hi Sathish,

Hope you are trying to archieve this

Ztotal =   100 * (N + n)

sample code

ztest-Field2 = N + n.

Ztotal = Ztest-field1 * Ztest-field2.
