Hi, new to Odoo I have made a template in custom XML 
my_addon/static/src/eg.xml

< templates id = "template" xml : space = "preserve" > 

    < t t-name = "Chrome" > 
        < div class = "pos" > 
            < div class = "pos-topheader" > 
                < div class = "pos- branding " > 
                    < img class =" pos-logo " src =" / point_of_sale / static / src / img / logo.png " /> 
                    <span class = "placeholder-UsernameWidget" > </ span > 
                </ div > 
                < div class = "pos-rightheader" > 
                    < span class = "placeholder-OrderSelectorWidget" > </ span > 
                    <! - here goes header buttons ->
 </ div >             </ div >
 </templates>                

 What I was trying to do is inherit it in another custom module.I have tried the below code 


< template id = "jfm_mod_receipt" name = "jfm_mod_receipt check" inherit_id = "point_of_sale.template" > 
    < xpath expr = "// div [@ class = 'pos-sale-ticket']" position = "after" > 
        < div class = "pos-center-align" > < t t-esc = "moment (). format ('L LT')" /> </ div > 
    </ xpath > 
</ template >
but it is showing error ParseError: "External ID not found in the system: point_of_sale.template" while parsing None:4, near <data name="jfm_mod_receipt check" inherit_id="point_of_sale.template"> <xpath expr="//div[@class='pos-sale-ticket']" position="after"> <div class="pos-center-align"><t t-esc="moment().format('L LT')"/></div> </xpath> </data> 

Kindly someone help me out
