Hello all
Scenario: I need to check the Invoice number in an Custom Object and if it is not unique it displays an error. But I am getting an error during in an execution. Could any one help on this??
Map<String, Claim__c> sclmap = new Map<String, Claim__c>();
//////////////////////////////////
//4 Unique Invoice number/////////
//////////////////////////////////
for(SObject obj: Trigger.new)
{
Claim__c cl =(Claim__c)obj;
cl.Unique__c=cl.Claim_Invoice_Number__c+cl.Claim_Invoice_Position__c
+cl.Claim_Document_Line_Item_Number__c+cl.Claim_Line_Item__c;
//////////////////////////////////////////////////
//Make sure we don't treat an Unique__c that isn't
//changing during an update as a duplicate////////
//////////////////////////////////////////////////
if( (System.Trigger.isInsert ||
(cl.Unique__c != System.Trigger.oldMap.get(cl.id).Unique__c)))
{
if (sclMap.containsKey(cl.Unique__c))
{
cl.InvoiceMessage__c = 'already Invoice is present';
}
else{
sclMap.put(cl.Unique__c, cl);
cl.InvoiceMessage__c = NULL;
}
}
}
//////////////////////////////////////////////////////////////////////////
//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.Error__c.addError('already Invoice is present');
newscl.InvoiceMessage__c = 'Invoice is already present';
}
I am getting this error 'Field expression not allowed for generic Sobject'
You cannot use direct reference or assignment when working with sObjects. Instead you must use their get and put methods.
So instead of
String strObjectName = mySObject.Name;
you need to do:
String.strObjectName = String.valueOf( mySObject.get('Name') );
Same applies to assigning values to sObjects. Instead of:
mySObject.Name = 'MyName';
you need to do:
mySObject.put('Name', 'MyName');
