Doubt in UDF

[Former Member]

am mapping dummy to a segment E1MAKTM-MAKTX.

Dummy is a field which will contain the text this text needs to be split for every 4 character and populate it into multiple E1MAKTM.

This is the requirement.

If the input is

Hi,

but I think that this code will not work for the last substring if the length is not a multiple of 4.

It's working in my code

Hi Patrick,

It worked. Now i need only more functionality in the code that it shoud not split in the space.

If the length we are considering is 10.

for the input " Thanks for answering my posts".

then the ouput should be

Is it possible to include this functionality also in the code

Hi,

after the startIndex += 4;

expression you just have to insert this while loop:

while (startIndex < a[0].length() && a[0].charAt(startIndex) == ' ') {

startIndex++;

}

I have tested the below code is working fine .Choose context while creating the UDF

String input1=input[0];
int cnt=4;
for(int i=0;i<input1.length();i++)
{
if(i+4<=input1.length()){
result.addValue(input1.substring(i,cnt));
 i=cnt-1;
 cnt=cnt+4;
}
}

Thanks guys..

i tried with Fathima's code. Am getting a runtime exeption when i clicked on Displyqueue of the udf i used

RuntimeException in Message-Mapping transformation: Exception:[java.lang.ArrayIndexOutOfBoundsException: 0] in class com.sap.xi.tf._Lennox_MDM_Material_create_2_MATMAS05_ method test$[com.sap.aii.mappingtool.tf3.CBufIter@20bed219]

what shall we do.

Hi,

this (context) UDF should work:

int startIndex = 0;

while (startIndex < a[0].length()) {

if (startIndex < a[0].length() -4)

result.addValue(a[0].substring(startIndex, startIndex + 4));

else

result.addValue(a[0].substring(startIndex, a[0].length()));

startIndex += 4;

}

Hi,

You can use the function substring to break the string . eg : for the first 4 characters substring(0,3) then next 4 characters substring(4,7) like that you break the string into small components.
