i facing following issue:
We Have Obj. Account and Obj. B__c. On Object Account we have a ID__c which stores an ID. Now we get this ID from an external System written in an text field on Obj. B__c
Now i need a piece of code which matches teh ID from Obj. B__c with the ID from Account and if a match is found the LOOKUP on Obj. B__c should be populated with the ACCOUNT NAME which has the same ID.
I hope it is undersantable and anyone can help me out with some link for ressources.
