Map<Id,Set<Id> Syntax

Map<Id,Set<Id>> NoIFC_Product_Map= new Map<Id,Set<Id>();

                       sli.Sample__c = sampleRecord.Id;
                       sli.Product_No__c=NoIFC_Product_Map.get(sli.Product_No__c); I want to access the id and get the set of ids,
I get the error  Illegal assignment from Set<Id> to Id when i use the Map.Get(Id).
Can you please help me out.
                       newSli.add(sli);
                }

Thanks

As per your map definition, you will get set<Id> as return value so  what you need to do is 
set<Id> temp = NoIFC_Product_Map.get(sli.Product_No__c);
Then you have to assign the value from this set to sli.Product_No__c.

Thanks for the reply.Can you please help me out how to assign 
sli.Product_No__c.=temp

Thanks for help

Hi Jyo,

Please find the corrected program.

Also added my comment whereever I modified with.

//MD - Modified
  
Map<Id,Set<Id>> NoIFC_Product_Map= new Map<Id,Set<Id>();
Set<Id> NoIFC_Product= new set<id>();
for(product2 Products:AllProducts_Query) {
	if(Products.Test__c) {    //MD - Modified
		NoIFC_Product.add(Products.Id);
		NoIFC_Product_Map.Put(Products.Id,NoIFC_Product);
		for(SampleLineItemExt sliExt : sampleLineItemExtList) {
			 Sample_Line_Item__c sli = sliExt.sampleLineItem;
			if(sli.Id != null) { // Product_Number__c replaced by Product_No__c
				if((sli.Product_No__c == null ) 
				&& (sliExt.iqty == null || sliExt.iqty.equals(''))
				&& (sli.Unit_Of_Measure__c == null || sli.Unit_Of_Measure__c.equals(''))
				) {
					delSliSet.add(sliExt.sampleLineItem.Id);
				}
			}
			if((sli.Product_No__c != null )&& (sliExt.iqty != null && !sliExt.iqty.equals('')) && (sli.Unit_Of_Measure__c != null && !sli.Unit_Of_Measure__c.equals(''))) {
				sli.Quantity__c = Integer.valueOf(sliExt.iqty);
				if(sli.Sample__c == null)
				   sli.Sample__c = sampleRecord.Id;
				   Set<Id> tempNoIFC_Prod = NoIFC_Product_Map.get(sli.Product_No__c); //MD - Modified
				   newSli.add(sli);
			}
		}
	}
}

Please do let me know if it helps.

Hi Jyo,

As you are getting the set of Ids, what do you want to achieve here, if you can explain the requirement, it will be easy otherwise we can assign 0 index value into it using below:

sli.Product_No__c =  (new list<Id>(tempNoIFC_Prod) )[0] );

or else

for (Id idVal : tempNoIFC_Prod) {
        sli.Product_No__c= idVal;
        break;
}

Mahesh

Thanks Mahesh,

But me need to assign the set of values to Sli.product__C=tempNoIFC_Prod  and that values to newSli list .How can this can be achevied.
Mahesh DMahesh D
Based on my understing
  
for (Id idVal : tempNoIFC_Prod) {
        sli.Product_No__c= idVal+',';
}

If Product_No__c is lookup or Master-Deatil you can not do what you are asking. If its a text field where you just want to store all possible Ids then you can use 

set<Id> temp = NoIFC_Product_Map.get(sli.Product_No__c);
for (Id idpno : temp) {
    sli.Product_No__c= idpno+',';
}

hello venky it's a  Master-Deatil  relation ship.

If needed how can achevie how this?

Thanks

Jyo
Mahesh DMahesh D
Hi Jyo,

If it is Master-Details then you can assign only one value to it.
  
for (Id idVal : tempNoIFC_Prod) {
        sli.Product_No__c= idVal;
        break;
}

Can you tell your exact requirement now. I see that you are placing voth productid and map of product ids into map which might not be required for your case.

Hello Venky,

I have sample ,Sample_line_item object .In sample _Line item object we have a lookup relation to product2 .
There is one field test__c on product ,
suppose if the user selects prodcuts A=true,B=false,C=false, A B,C,
I need to insert A B C ,B,C in the sample_line_item. 

Thanks

Regards,
Jyo

If you have lookup to Product2 on Sampleline, you can select one Product. How can you select more products..is is a junction object like you have sample as one object and product and then you have sample line item that stores prodcut and sample ?

IFU_DUP>>>> (01t50000002atr0AAA, 01t50000002at1TAAQ, 01t50000002at1UAAQ, 01t50000002at1YAAQ, 01t4B000000sTKMQA2, 01t50000002at1TAAQ, 01t50000002at1UAAQ, 01t50000002at1YAAQ)>>>>>> {}

LstProduct=[Select id,Name,Test__c from Product2 where Id=:IFU_DUP and BOM__c=false];
I am passing two identicals ids aganist the product ,I want the query to retun the list twice.

LstProduct=[Select id,Name,Test__c from Product2 where Id=:IFU_DUP and BOM__c=false];
            System.debug('  LstProduct>>> '+LstProduct.size()+' >>>>> '+LstProduct);

LstProduct>>> 3 >>>>>  here the list should be 6 but i am getting 3 values i know i am passing the same ids.
Is there any way the the list will loop to get all the records in the query.

Thanks for the help.

Regards,
Jyo
 
venkat-Dvenkat-D
What do you mean you want the query to return twice? Query once and you can add them to new list twive

list<Product2> duplicateProds = new list<Product2>();
duplicateProds.addall(listProd1);
duplicateProds.addall(listProd2);

But I am not sure why you need same records twice in the list.

Hi Jyo,

Can you paste the actual requirement and your exists trigger / class / vf page so that we can able to understand.
