Nash12345 Updating Account lookup field upon creating record
Hello my fellow salesforcers,
I'm trying to auto-populate an account lookup field on a custom object (purchase item) based on the account field on its parent object (purchase order) which, in turn, is a child object to account.
What I know is workflows don't allow lookup field updates. I also know, or I think I know, that process builder cannot realise this action because the trigger for the auto-population to happen is based on an event prior to the purchase item record being created.
So am i right to assume that the only way to achieve what I'm looking for if via an apex trigger with the "before create" at the top?
If so, is the following code suitable? I'm currently getting an error on line 11 as it is unable to recognize the relationship of the purchase order's account (supplier) lookup field:
trigger AutoPopulateAccountLookupOnPi on Purchase_Item__c (before insert, before update) {
//get the Purchase Orders Id's and store it in a set.
set<Id> POIdSet = new set<Id>();
for(Purchase_Item__c co: trigger.new){
if(co.Purchase_Order__c != null){
opptyIdSet.add(co.Purchase_Order__c );
}
}
//query the purchase order records and get the associated accounts.
map<id, Purchase_Order__c > POMap = new map<id, Purchase_Order__c >{[SELECT id, Purchase_Order__r.Supplier__c FROM Purchase_Order__c WHERE Id IN: POIdSet]};
//update the account value based on the purchase order in the record.
for(Purchase_Item__c co: trigger.new){
if(POMap.containsKey(co.Purchase_Order__c )){
co.Account__c = POMap.get(co.Purchase_Order__c ).accountId;
Thanks in advance!
