lizmijohn Update/add/delete child records on parent field's start and end date change
Hi,
Please help me with my requirement as follows:
Parent object: project
Child object :Project analysis
Trigger on :Project analysis
Scenario 1: Parent object (start date=1/6/2011 and end date=1/1/2012)
On Insert Project analysis will have records with date values as
PA 1 : Date-1/6/2011,PA 2: Date-2/7/2011, PA 3: Date-2/8/2011,...PA 19: 10/12/2012.
On Update if I change Parent object's (start date=1/5/2011 and end date=1/1/2012) then the value are as follows:
PA 1 : Date-1/5/2011,PA 2: Date-1/6/2011,...PA 18: 9/10/2012, PA-19: 10/12/2012
As per my understanding on change of parent object's start and end date, the child records are not incrementing or decrementing accordingly to take the correct date values.
My code is as below:
if(trigger.isupdate){
List<Project_Analysis__c> listPA= new List <Project_Analysis__c> ();
List<Project_Analysis__c> tbuPA = New List<Project_Analysis__c>();
listPA = [Select Project1__c,Amount_Per_Month__c,Date__c,Start_Date__c FROM Project_Analysis__c WHERE Project1__c IN :trigger.new];
for (Project1__c np : trigger.new) {Integer j = 0;
date NewDate=np.Start_Date__c;
date upDate1=NewDate;date Test;
for (Project1__c oProject : trigger.old){
for(Project_Analysis__c lPA : listPA){
if (lPA.Project1__c == np.id && ((np.Project_Value_per_month__c != lPA.Amount_per_month__c)&&(np.Start_Date__c!=lPA.Start_Date__c))){
lPA.Amount_per_month__c = np.Project_Value_per_month__c; if(np.No_of_months__c!=oProject.No_of_months__c){
if(j <= (np.No_of_months__c)){
if(upDate1< np.EndDate__c.addDays(25)){
lPA.Date__c = upDate1;
upDate1= upDate1.addDays(31);
}
}
j=j+1;
tbuPA.add(lPA);
}
}
}
}
}
if(tbuPA.size() > 0)
update tbuPA;
}
Thanks in advance
the logic you have writter will update the child records only if "No_of_months__c" field is changed.
there are many other conditions. But I think this is the problem area or was this part of your requirement.

Based on 'No of months' field change, the code has to be modified. I am not a developer. So would like to get some help on this area.
The code you have written is unnecessery complicated.
You can post your detailed requirement I will get you the code with simple logic.

if possible post with example.

I have a parent object: Project
Child object: ProjectAnalysis
On insert Project fields will be entered
Project value=60000
Start date=1/6/2011
End date=1/6/2012
No: of months=ROUND(((( EndDate__c - Start_Date__c ) / 30)+0.5),0)
Project value per month=ROUND(( ProjectValue__c / No_of_months__c ),0)
On save a trigger is initiated that creates child object (project analysis records)
PA-id, Amount per month=Project value per month,Date=1/6/2011
This way it has to repeat till( End date+25) is reached. Can be seen in my code.
On Update of start date to 1/7/2011 then child records should take dates from 1/7/2011 and ends in 1/6/2012. It should reduce child records count to 12 now. This way on change of start date /end date the child record should change by taking correct date values.
Please let me know if any questions.
Any help on this soon will be appreciated.
Thanks
need to clear one more thing.
if the project period is extended you may need to add new records for Project analsys and if it is reduced you may need to delete additional.
or you expect the project dureation to remain constant?
Yes, if the project duration is more then records need to be added else reduced. Project duration may not be constant.
Hi,
I am looking in this. will update you soon.
