File to IDOC Senario (Message Mapping)

Question

Hi Experts,
I am a fresher.
This is "  File to IDOC Senario  ".
I have Doubt on  this: ( In Message Mapping)
Source field : MSG
Length : 1/264
Taget field : E1EDKT2 - TDLINE
Legth : CHAR/70
Mapping Condition :
Note: TDFORMAT =  ‘=’ (Long Line), until next line of MSG. When new line occurs in MSG, then use TDFORMAT = ‘/’
How to Make the Mapping for this?
Anyone Can help me to get it Quickly.
give your Suggestions and Show some Example Mappings......

Hi ,
Below is the generic sol for your problem .Graphical mappings wont workout for your problem while using sub string .
Input -->Input string
Length -->length of TDLINE
MESSAGE_V1,V2,V3,V4....depends on how many TDLINES you expect .Here I have taken 4 .
public void SplitbyLength(String[] Input, String[] Length, ResultList MESSAGE_V1, ResultList MESSAGE_V2, ResultList MESSAGE_V3, ResultList MESSAGE_V4, Container container) throws StreamTransformationException{
int lengthVal = Integer.parseInt(Length[0]);
int InpLenVal ;
for(int i=0;i<Input.length;i++)
InpLenVal  =Input[i].length() ;
if (InpLenVal<=lengthVal)
MESSAGE_V1.addValue(Input[i].substring(0));
MESSAGE_V2.addValue(ResultList.SUPPRESS); 
MESSAGE_V3.addValue(ResultList.SUPPRESS); 
MESSAGE_V4.addValue(ResultList.SUPPRESS); 
else if ((InpLenVal>lengthVal) && (InpLenVal <= (lengthVal*2)))
MESSAGE_V1.addValue(Input[i].substring(0,lengthVal));
MESSAGE_V2.addValue(Input[i].substring(lengthVal,InpLenVal));
MESSAGE_V3.addValue(ResultList.SUPPRESS); 
MESSAGE_V4.addValue(ResultList.SUPPRESS); 
else if ((InpLenVal>(lengthVal*2)) && (InpLenVal <= (lengthVal*3)))
MESSAGE_V1.addValue(Input[i].substring(0,lengthVal));
MESSAGE_V2.addValue(Input[i].substring(lengthVal,(lengthVal*2)));
MESSAGE_V3.addValue(Input[i].substring((lengthVal*2),InpLenVal));
MESSAGE_V4.addValue(ResultList.SUPPRESS); 
else if (Input[i].length()>(lengthVal*3)  && (InpLenVal <= (lengthVal*4)))
MESSAGE_V1.addValue(Input[i].substring(0,lengthVal));
MESSAGE_V2.addValue(Input[i].substring(lengthVal,(lengthVal*2)));
MESSAGE_V3.addValue(Input[i].substring((lengthVal*2),(lengthVal*3)));
MESSAGE_V4.addValue(Input[i].substring((lengthVal*3),InpLenVal));
else if (Input[i].length()>(lengthVal*4) )
MESSAGE_V1.addValue(Input[i].substring(0,lengthVal));
MESSAGE_V2.addValue(Input[i].substring(lengthVal,(lengthVal*2)));
MESSAGE_V3.addValue(Input[i].substring((lengthVal*2),(lengthVal*3)));
MESSAGE_V4.addValue(Input[i].substring((lengthVal*3),(lengthVal*4)));
