Splitting Messages in SAP PO using a Java Mapping

Splitting Messages in SAP PO using a Java Mapping

Here is an example of a Java mapping in SAP PO that splits a message using the String.split() method:

import java.util.Arrays;

import com.sap.aii.mapping.api.*;

public class MessageSplitter extends AbstractTransformation {

    public void transform(TransformationInput input, TransformationOutput output) throws StreamTransformationException {
        try {
            // Get input and output payload
            InputPayload in = input.getInputPayload();
            OutputPayload out = output.getOutputPayload();

            // Read input message into a string
            byte[] bytes = new byte[in.getInputStream().available()];
            in.getInputStream().read(bytes);
            String inputMessage = new String(bytes);

            // Split message using a delimiter
            String delimiter = ",";
            String[] parts = inputMessage.split(delimiter);

            // Write the parts to the output payload
            for (String part : parts) {
                out.getOutputStream().write(part.getBytes());
            }
        } catch (Exception e) {
            throw new StreamTransformationException(e.getMessage());
        }
    }
}

In this example, the input message is read into a string, then split using the comma (“,”) delimiter. The resulting parts are then written to the output payload, one after the other. You can change the delimiter to any string you want to use as a separator.

Please keep in mind that this is just an example and it may need further adaptation depending on the specific requirements of your integration scenario
