Hi @Anjali_Rani

1. Assign activity:
dictCopy = yourDictionary.ToDictionary(Function(entry) entry.Key, Function(entry) entry.Value)

2. For Each kvp In dictCopy
    If conditionToCheck(kvp.Value) 
    Then
           dictCopy(kvp.Key) = newValue

3. For Each kvp In dictCopy
    yourDictionary(kvp.Key) = kvp.Value

Hope it helps!!

For Each keyName in yourDict.Keys

  • Assign yourDict(keyName) = “some value”

This shouldn’t give you any issues because you’re looping through the array of keys.
