Hi Yakito,

You can convert your .sxw file into .rml file by the help of openerp_sxw2rml. You can find it in base_report_designer module.

1. Create a simple .sxw file. No loops or no programming code in it. Just simple title of report.

2. Go to terminal & go to openerp_sxw2rml module path. Then write below command

   python openerp_sxw2rml.py your_sxw_file_path your_rml_file_path

   here, your_rml_file_path is to create .rml file of your desired path.

3. Now your .rml file is ready. Now you just need to create report tag in report.xml file

   <report
       auto="False"
       id="report_id"
       menu="True"
       model="object.object"
       name="report_name"
       rml="your_rml_path"
       string="Your Report String"/>
   

   Now just restart the server and update your module. Then you can see your report in your object form view shortcut, the object you've specified in your <report></report> tag.

Hope now your report will work.

Thanks.
