Is it possible to use one infopath form in order to send data to many sharepoints list
Yes, I succeeded to submit data from one Infopath form into 2 different lists following
Only I created 2 XML files (instead one in above article) for respectively 2 receive data connections from them (instead 1 in article)+ 2 sharepoint lists (instead 1) respectively
Respectively added 2 submit data connections to http://sharepointserver/_vti_bin/lists.asmx webservice, instead 1 in article
I did not insert Submit button, as in the article (since it is redundant to already built-in ribbon's Submit button) having used "Submit Options"
Perform custom action using Rules
To set rules that will run when a user submits the form, on the Data tab, in the Rules group, click Form Submit
having added to Form Submit a rule that "Run these actions:" "Submit using a data connection" having added the above created 2 submit data connections
to a webservice.
