data conversion questions

[Former Member]

Hi Everyone,

I'm confused by the data conversion rule and how to do it in abap, could you help me about some of my questions?

1. How many ways to do data conversion ( like assignment .....)?

2. When using field symbol, we know we can assign reference to field symbol , and at mean time , we can casting type.

Is this kind of casting also a way to do data conversion?

3. In my real case, I have unknown type data to convert to xstring. the type could be any ( I, D, T, STRING......). Is there an easy way to implement that when I get the data reference, I only need to import it to a method and then the method return an xstring to me?

4. question 3 is about data->xstring, and how can I convert xstring back to the original data( should be the same type )?

Thanks and Regards,

Aaron

Hi Aaron,

concerning question 3./4. you could have a look at Function Group SCMS_CONV, where you find Function Modules like

SCMS_STRING_TO_XSTRING

SCMS_XSTRING_TO_BINARY

Perhaps that helps,

Hi Aaron,

try this FM: CONVERSION_EXIT_ALPHA_INPUT

is useful for convert different data type, here an example:

call function 'CONVERSION_EXIT_ALPHA_INPUT'

exporting

input = A ( type unknown )

importing

output = B ( type xstring ).

Perhaps that helps,
