Function modules RS_CONV_EX_2_IN, RS_DS_CONV_IN_2_EX

[Former Member]

Hello,

Kindly advice me what is the use / purpose of SAP Function modules RS_CONV_EX_2_IN and RS_DS_CONV_IN_2_EX ?

I think they work only for character data type input. What about other data type like currency ?

Thanks,

Go to SE37 and enter both function module names.

You should get all the information you need from there.

Hello,

Yes, I have debugged these function modules. But need some details about them.

My question:

I have one field on my screen which is character 20. I am putting some amount into this field.

Now I want to check the input entered by used whether it is valid or not.

Since the screen field is character, user can input anything.( I mean some alpahbets and other character other than number).

I want to accept only numeric values and reject any alpahbets and character other than

'0123456789.,'.

Please advice me 1) How can I do it?

2) Whether the above function modules will be useful for it?

Thanks and rgds,

Anand

You can check that there are only digits before passing to the function modules.

IF field CN '0123456789'.

MESSAGE 'Not a numeric value' TYPE 'E'.

ENDIF.
