Mapping issue: Split a string to multiple strings in an idoc

[Former Member]

Hi,

I need to split a string with an undefined length into strings of 132 chars. The problem is, how to map from the source field to the target field,

which belong to an idoc segment. The segment has the occurence 1 to unbounded, and the field 0 to 1. Simplifying, i need to map one source field split it in 132

chars block and put the resultant blocks into an idoc field (maxLength = 132).

-

IDoc

Segment X

...

Segment (occurence 1..unbounded)

-

Field X

Source field SourceA (undefined length)----->-----Field TargetA (occurence 0..1) (maxLength = 132)

-

---

Segment Y

Ok...here is one way of achiving what u want - hope ur comfortable with working with context mapping...

Raise the context of ur source field one level higher and write a UDF funtionto do this -

Declare an array list

Read the source string and append it to the arraylist.

Then when u map ur target IDOC text...read from this array list and created ...By maintaining the context...there will be as many segments in the idocas there are in the arraylist..

Hi Jose,

You can achieve this via writing a simple UDF in your mapping.

I developed a UDF, that returns an array with multiple blocks of 132 char, however, only the first one map wtih the target.

Can you give me some more information to solve my problem?

Thanks.

Jose,

Create a Context user defined function AddNode. Have one argument input and add this code:

String str=input[0];

while(str.length()>132)

{

result.addValue(str.substring(0,132));

str=str.substring(132,str.length());

}

result.addValue(str);

Combine the Arvind Ravindran answer with Satish Reddy answer and we have the solution.

Thank you both.
