Hi Team,

WorkPage.Customerse(1).IncometDocumentList(4).CashtDeposit(1).Unpyledged

erorr: Fail: in in RULE-OBJ-WHEN @BASECLASS: Index: 3, Size: 0

@RaghavN2 - In clipboard thread the exactly same structure present which was mentioned in when? For verification try adding a text input on the field and pass the same property to verify what data is present. This way will know issue is with syntax or with the property not present in Clipboard.

Thank you.
