Displaying type dec when value = 0

Former Member — Thu, 30 Dec 2010 09:20:48 GMT

I have a variable which is of type dec. When 0 is entered as a value, the value displays as a blank field whereas I want to display as 0.0 - but only if 0 has been entered as a value. Can this be done?

Hi Kevin,

Can you be more specific - as in where do you want to display this field. Is it in an alv report or module pool screen etc ?

There are a couple of operations for ALV reports that can get this output.

Please specify your requirement.

It is a module pool screen. I have got round the problem by declaring the type as char (with a range stipulating numeric values only) and writing the dec value or clearing the field as appropriate. It is a rather messy solution though and if there is another way I would like to know what it is.

I have come with an approach but to be honest I think your original is probably better.

I have basically worked with character fields but created them in the dictionary and used

conversion exits.

I created a data element ZNRW_CHAR5 using a domain of the same name.

The domain ZNRW_CHAR5 is type CAHR length 5 but has an output length of 6 and uses a convers routine of ZNRW5.

I created a local function group which contained two function modules which have the same interface:

an untyped importing parameter 'input' and a simlar exporting parameter 'output'.

CONVERSION_EXIT_ZNRW5_INPUT...the only code in this is: output = input.

CONVERSION_EXIT_ZNRW5_OUTPUT...has a bit more code

data l52(3) type p decimals 2.

data l_string(6) type c.

clear output.

if input co ' 1234567890.'

and input is not initial.

write input to l_string.

l52 = l_string.

output = l52.

endif.

I created a test abap:

REPORT ZNRW_TEST_CONV_EXIT.

parameters: p_char type ZNRW_CHAR5.

write:/ '''' no-gap,p_char no-gap,''''.

This works but I think it's messier than your origianl. Maybe it could be cleaned up a bit??
