Hi ,
I have got a requirement to convert the below Java code in Apex. This is to flatten multivalue for row level security. Any suggestion/help will be appreciated. Thanks.

I have been trying to get data through a http callout in batch class. its giving max callout time 120000 exceeded errorr any  suggestion on how it can be fixed?

Hi,

I want to create a vf template which will have collated opportunity/relatedobject information of a user.

It will be like

dear user.

your following opportunities and relatedobject__c are due. Please check their planned and approval dates.

Opportunity Object Table with 

Opportunitiy id, planned date, approval date


relatedobject__c  table with 

relatedobject__c id, planned date approval date

Regards,
Salesforce

The above template should be scheduled to send information everyday with the following condition..

All opportunities of a owner where planned date is less than today and approved date is missing

All relatedobjects of a owner where planned date is less than today and approved date is missing

Please guide...

There are two Objects:
1.Property__c(obj) with fields Status__c(Picklist) and Ajent__c(lookUp to Contact)
2.Contact (obj)
Scenerio:
Contact obj has some records 
if user change status__c of property form 'open' to 'working' the, If that user have a contact record, Agent__c field should get populated with that Contact Name field.  

Need some guidance or a piece of code for the below mentioned scenario,

everyday at certain time, lets say at 9 am I want to send an email to opportunity owners with all their opportunities where amount is updated to 20000. so if one owner has 20 opportunity and has 20000 amount in each, then it will collate all these opportunity with their name and amount field and frame one email and send to the owner.

Please help me with the code if possible..
 

Hi, I am trying to combine two picklist values from two different objects for selection on my vf page.

let's say, I have an object opportunity with Stage picklist

there is another object as "Order Intake" which is the child of opportunity; it has a picklist which says if the oif days are due by options:
10 days
20 days
30 days

I am creating a picklist for vf page as 'Select category' where I want options as Stage values + Order Intake values;
when I select the options it should display respective Order Intake or opportunity.

Please assist

Hi,

I want to edit opportunity record and its related child record at the same page in vf; once I check the opportunity it should show its related child record and allow me to make changes to both opportunity and child record. Currently I can do it on two separate pages. below are the current lines of the code for apex and vf.. also, I should be able to manage the colums properly on my page so that i dont need to scroll the page..Please assist..
