EPM ADD IN RIBBON EXTENSION

Hi,

I 'm using EPM ADD IN 10.0 SP 16 Patch 1 For Excel.

I'm trying to insert a custom button that call a macro in a .xla file.

I've followed the tips founded in epm add in help , at Ribbon Extensibility section.

This is my RibbonXML.xml file

<EPMTab xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance

xmlns:xsd=http://www.w3.org/2001/XMLSchema

xmlns=http://xml.sap.com/2010/02/bpc>

<Group>

<label>MyBar</label>

<Component>

  <type>ToggleButton</type>

  <label>SaveExcelFile</label>

    <onAction>MyFile.xla!StartCopyValues</onAction>

  <isEnabled/>

</Component>

</Group>

</EPMTab>

I've copied this file on \%userprofile%\AppData\Local\EPMOfficeClient\ but it  doesn't work

Anyone have experience with simple Ribbon Extension in Epm Add in

Thanks

Samuele
