@SatishKumarC17070052 - Verify the data page rule and try unchecking “reload once per interaction” in the load management. This issue will be seen in some scenarios like if we have same source table multiple on same screen. This will give inconsistent results and functionality breaks. ---

@Priyanka Boga “reload once per interaction” is already unchecked, and based on a dropdown selection table data will be changed ---

@Priyanka Boga Yes it is unchecked, this is a List type Data page with editable mode and RD as a source. ---

@SatishKumarC17070052 Is it working with the static records ? something like without any dependency load the table standalone and try filtering? Want to understand is the issue with table source or dynamic data behavior. Thank you. ---

@Priyanka Boga I found the issue, the selected dropdown value is not storing on the clipboard page on first selection after changing the selection or refreshing the section property value is storing on the clipboard page, because of this filters are throwing NullPointerException exception for value missing on initial check.
