Hello SDN,
I need some help with a user-defined function. My source message contains multiple
generic records (1000 char string), and my target message is 1 header record,
then multiple generic records. See description of source and target messages below:
Source:
GenericRecordTable 1..unbounded
Row (1000 char string)
Target:
Field1 (char5)
Field2 (char5)
Field3 (char5)
IT_Data
GenericRecordTable 1..unbounded
Row (1000 char string)
Basically, what I need to do in my user defined funtion is to map the first record
in my source record to the 3 header fields, then map all of the rest of the records
(starting from line 2) into the GenericRecordTable.
Can someone please help me with the code for the user defined function(s) for this
mapping?
Thank you.
Hi,
If i have understood your question correctly then it can by achieved by using the substring function.
I mean take the required value from your Record (1000 char) by using substring and map it to your field1, field2 & field3. Like this for example.
Row (1000 char) -
> Substring (0, 5) -
> Field1.
Row (1000 char) -
> Substring (6, 11) -
> Field1.
Row (1000 char) -
> Substring (12, 17) -
> Field1.
IT_Data
GenericRecordTable 1..unbounded
Row (1000 char) -
> Substring (18, 1000) -
> Row (1000 char)
Please correct me if I have understood it wrong.
Regards,
Sarvesh

Hello, I don't think you understand how my source data looks like. See below.
aaaaabbbbbccccc
this is generic record line number 1
this is generic record line number 2
this is generic record line number 3
...
I am new to Java, so I need help with the coding of the UDF to read the first line in my source message and map it to the header fields in my target message. Then I think I will need a second UDF to read the other records starting from second line in my source message and map them to the table in my target message.
If you can help, I would really appreciate it.
Thank you.
hi,
Activities
1. To create a new user-defined function, in the data-flow editor, choose Create New Function (This
graphic is explained in the accompanying text), which is located on the lower left-hand side of the
screen. In the menu, choose Simple Function or Advanced Function.
2. In the window that appears, specify the attributes of the new function:
Name
Technical name of the function. The name is displayed in the function chooser and on the data-flow
object.
Description
Description of how the function is used.
Cache
Function type (see above)
Argument Count
In this table, you specify the number of input values the function can process, and name them. All
functions are of type String.
3. In the window that appears, you can create Java source code:
...
a. You can import Java packages to your methods from the Imports input field, by specifying them
separated by a comma or semi-colon:
You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since
all message mappings require these packages and therefore import them. You should be able to
access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the
package under Import. In other words, you do not have to import it as an archive into the Integration
Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the
SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
In addition to the standard packages, you can also specify Java packages that you have imported as
archives and that are located in the same, or in an underlying software component version as the
message mapping.
b. Create your Java source text in the editor window or copy source text from another editor.
4. Confirm with Save and Close.
5. User-defined functions are limited to the message mapping in which you created the function. To
save the new function, save the message mapping.
6. To test the function, use the test environment.
The new function is now visible in the User-Defined function category. When you select this category,
a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the
function to the data-flow editor, choose the arrow next to the button and select from the list box
displayed.
