suneel.patchipulusu@gmail.com How to check the existing field value in an custom Object?
Hello All
Scenario: I have an Invoicenumber field (its an text data type).So, every user enters his data and save the record. After saving the record it will display the red or green flag
red-- indicates invoicenumber already exists,
Green--- indicates not exists the invoicenumber so no problem.
I dont want to use Unique check box. Through trigger I like to check whether this Invoicenumber already exists in custom Object or not
Could any one have any idea???
Please share ur suggestions?
Thankyou
for(Claim__c s : Trigger.new) {
s.Unique__c=s.Claim_Invoice_Number__c+s.Claim_Invoice_Position__c
+s.Claim_Document_Line_Item_Number__c+s.Claim_Line_Item__c;
}
Map<String, Claim__c> sclmap = new Map<String, Claim__c>();
for (Claim__c scl : System.Trigger.new){
//////////////////////////////////////////////////
//Make sure we don't treat an Unique__c that isn't
//changing during an update as a duplicate
//////////////////////////////////////////////////
if( (System.Trigger.isInsert ||
(scl.Unique__c != System.Trigger.oldMap.get(scl.id).Unique__c)))
{
if (sclMap.containsKey(scl.Unique__c))
{
scl.Unique__c.addError('already Invoice is present');
}
else{
sclMap.put(scl.Unique__c, scl);
}
}
}
//////////////////////////////////////////////////////////////////////////
//Using a single database query, find all Invoice nos in the claim table
//that have the same number as any of other claims being inserted or updated
////////////////////////////////////////////////////////////////////////////
for(Claim__c c : [select Unique__c from Claim__c
where Unique__c IN : sclMap.KeySet()] )
{
Claim__c newscl = sclMap.get(c.Unique__c);
newscl.Unique__c.addError('already Invoice is present');
}
I tried like this but the above mentioned code finds the duplicate Invoice number but I need to show this error after saving the record, here from the above code I am not able to save it throws an error
Please give some suggestiions on this??

How it display red or green??
It displays through if Invoicenumber is null after update it shows red.otherwise green
HI Suneel,
Can you Please elaborate your requirment .As per my knowledge u cannot set a flag green/red thrugh trigger.
But if you are using some satndard VF page which will override then u can set the forecolor (Invoice Number Field) to red or green after the save action of that record.
Please let me know the requirment and post it if the above solution is fine for you.
Regards,
Itsaws.
Hello
For seeting red and green flags
IF (ISBLANK(Unique__c),
IMAGE("/img/samples/flag_red.gif","Red", 20, 20),
IMAGE("/img/samples/flag_green.gif","Green", 20, 20)
)
But the ISBLANK is not current in my situation any way the user entering the Invoice number and after clicking the sava button it has to show whether the Invoice number is already exists in the object or not.
For this I am using two custom fields
1. Invoicenumber__c(user enters in to this)
2.after clicking save
3.Unique__c (this field displays red or green flag)
Both the custom fields availble in same object.
I tried with seeeting vlookup but doesnt help
Is it possible to do in Force.com
Thanks in advance
for(Claim__c s : Trigger.new) {
s.Unique__c=s.Claim_Invoice_Number__c+s.Claim_Invoice_Position__c
+s.Claim_Document_Line_Item_Number__c+s.Claim_Line_Item__c;
}
Map<String, Claim__c> sclmap = new Map<String, Claim__c>();
for (Claim__c scl : System.Trigger.new){
//////////////////////////////////////////////////
//Make sure we don't treat an Unique__c that isn't

if( (System.Trigger.isInsert ||

{
if (sclMap.containsKey(scl.Unique__c))
{
scl.Unique__c.addError('already Invoice is present');
}
else{
sclMap.put(scl.Unique__c, scl);
}
}
