[sonalis-ic]

Hi Himanshu, scenario 7, since trigger is on afterupdate, it is giving me error as "Record is read-only", can you please help, as it might be going to a recursion after i update the amount, which is not happening.

[sagarr]

Hi @salesforce make sense it is 3:07 am here in est, i was battling with scenario 13 for more than 4 hr and hell no i have learned so manythiings on Trigger.old and Trigger.old variables. They can't be used in SOQL direclty like IN: trigger.old the query returns 0 results. We need to access the values of the record and then we need to use.

Thanks

Hi Brother, I created Google Maps in Flow Builder, how can add it in my accounts records..I mean it will show Accounts address record

[rishabhgupta]

Hi Himanshu! In use case 21, you implemented "for(Con : newRecords)" I tried the same way but getting duplicate variable error. Also, in line number 71 we're just putting accountId as a key and Account as value. Correct?

[rockyomkar]

i cant stop laughing while seeing the usecase 25😄😄
