System Administrator 393 Setting Values of a LookUp Field
I have a look up called Credit Rating and that is supposed to generate Ids such as AB4, CB5. I am writing an apex class that derives these IDS based on other nuerical fields. However, I am making a string and the string has to be assigned to the Id data type as the field Credit Rating is a look up field with data type Id. I tried to cast it like this but it keeps showing me this error
"System.StringException: Invalid id: AD6()" , please help.
"System.StringException: Invalid id: AD6()" , please help.
Since Credit Rating is a look up field, you should assign salesforce record id to that id field.
I am assuming there is a string field X on Credit Rating which will have this values AD6, etc.
I dont know the exact requirement. So there are two possible ways.
1) You already have this Credit Rating record with AD6 string.
In this case, you can write a SOQL query after s= 'A' + 'D' ... line.
List<Credit Rating API name> listCR = [Select id from Credit rating api name where X =: s limit 1];
and then you can map this id as follows:
if(l!istCR.isEmpty()){
a.genesis_Credit_Rating__c = listCR[0].Id
}
2) There is no existing record and you have to create record at runtime and assign the id
In this case, you have to create a new record.
Credit Rating API name objCR = new Credit Rating API name(X=s, ....all the required fields);
insert objCR;
and assign this inserted record id to the a.genesis_Credit_Rating__c.
Hope this helps!
