Sample code to fill the target field with spaces

[Former Member]

Hi All,

Can anyone has sample code to fill the target field with spaces? I have many fields where I need to fill with spaces like 30,164 like that.

Thx

Navin,

use this simple udf. The input will be a constant containing the number of spaces you want .Let this input parameter be Blanks.

String returnBlank="";
for(int i=0; i<Blanks;i++){
   returnBlank=returnBlank+" ";
}

return returnBlank;

Hi Bhavesh,

I get the following error when I use sampel code below:

H:/usr/sap/RXI/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Map0478a140eabb11dbb905001143eeb19b/source/com/sap/xi/tf/_test_source1_target2_.java:42: <b>operator < cannot be applied to int,java.lang.String for(int i=0; i<Blanks;i++){ ^ 1 error</b>

Please let me know how to resolve this?

Thx

Navin

Your input (in the case, Blanks) is of String type. You'll have to parse it b4 you can use it.

...
int Blanks = Integer.parseInt(input);
...

where <i>input</i> is the input field.

But, IMHO, you should use MapWithDefault standard field instead.

Hi,

you can change to:

int numerofblanks = Integer.parseInt(Blanks);

String returnBlank="";

for(int i=0; i<numerofblanks;i++){

returnBlank=returnBlank+" ";

}

return returnBlank;

Hello Navin,

The reason you are getting this error is Blank is string and I is integer.

U need to convert Blank to Integer first using:

int B = Integer.parseInt(Blank);

then use B instead of Blanks in the forloop

Thanks,

Himadri

Hi Henrique,

Can I use MapWithDefault in my case?

Thx

Sure can!

Just enter in it the value you want it to input whenever an empty field comes.

From http://help.sap.com/saphelp_nw2004s/helpdata/en/43/c4cdfc334824478090739c04c4a249/frameset.htm :

<i>

Replaces empty contexts in the inbound queue with a default value, which you specify in the function properties.

Example:

If “Default” is the default value and

A|B1,B2| |C| |D

is the inbound queue,

mapWithDefault returns the following outbound queue:

A | B1,B2 | Default | C | Default |D.

The function corresponds to the following combination of standard functions:

If(

[]field,

exists([]field),

Constant([value=default]))</i>

So, just click twice on the MapWithDefault field and enter your 30 spaces or whatever. It will fill empty fields with it.

But, for it to work, your empty field will need to be unique in the context, meaning, it must have max occurrence of 1 and be inserted in the unbounded tag. If thats not the case, just use the udf.

Regards,

Henrique.
