Infopath - Repeating Table Merging Issues

I have an InfoPath Form that has a repeating table in main field and in web service which I call to send-receive the data. Now I have an issue that when I call the web service the repeating table data does not merge when multiple items are inserted, It takes only first field's value with repeating table in web service. I have a question that How to merge multiple data that can be merged using repeating table?
