    reRender="pbstracc,pbssdsacc" status="sdsAccButton"/> 

<apex:outputPanel id="pbssdsacc">

        <apex:outputText label="Customer" value="{!customerDetails.Name}"/>
        <apex:outputText label="Customer Code" 
            value="{!customerDetails.KUNNR__c}"/>
        <apex:outputText label="Address" 
            value="{!customerDetails.Street_1__c} 
                   {!customerDetails.Street_1__c} 
                   {!customerDetails.Street_2__c} 
                   {!customerDetails.Town__c} 
                   {!customerDetails.State__c} 
                   {!customerDetails.District__c} 
                   {!customerDetails.PIN_code__c}"/><br/>
        <apex:input type="date" label="From Date " 
            value="{!accountFromDate}" style="width:120px;font-size:12px" />
        <apex:input type="date" label="To Date " 
            value="{!accountToDate}" style="width:120px;font-size:12px" />
        <apex:commandButton value="Generate Report" 
            action="{!generateSDSAccountDetails}" 
            styleClass="btn btn-primary btn-sm" reRender="pbssdsacc"/>
    </apex:pageBlockSection> 
    <apex:outputPanel>
        <apex:pageBlockSection rendered="{!sdsAccountGenerateReport}">
            Customer Name
        </apex:pageBlockSection>
    </apex:outputPanel>                                 
</apex:outputPanel> 

Onclick of SDS Account button I want to rerender pbssdsacc which is working fine. But on click of Generate Report I want to show the pageblock section which is not displayed on click of SDS Account button but displayed on click of Generate Report button

Answer 1

You need following change to your code. You need to give id to parent outputPanel of your pageBlockSection

<apex:outputPanel id="pageBlockSectionParentDiv">
    <apex:pageBlockSection rendered="{!sdsAccountGenerateReport}">
        Customer Name
    </apex:pageBlockSection>
</apex:outputPanel>                                 

and then you should use that id in rerender comma separated list

<apex:commandButton value="Generate Report" 
        action="{!generateSDSAccountDetails}" 
        styleClass="btn btn-primary btn-sm" reRender="pbssdsacc,pageBlockSectionParentDiv"/>
