Is this interface a standalone interface, or is it being used as a component within a parent interface?

If it is a child interface, there’s a possibility that ri!cancel is being passed a constant from the parent interface. Since constants are read-only, attempting to save a value into ri!cancel will result in an error.

Similarly, if this interface is being called from a process model, check whether the process is passing a constant instead of a writable process variable.

Otherwise, could you provide some context of where and how this interface is used?

    I made ri!Cancel from constant to dynamic, this fixed it.

    Hi [mention:eef68e60a0d842ddadd0bbcaff199a4c:e9ed411860ed4f2ba0265705b8793d05] ,

    First save your result in the local variable and use save with local, e.g., a!save(local!TR_Expense_details.hrApproval, now()), and then save this to the rule input a!save(ri!TR_Expense_details.hrApproval, local!TR_Expense_details.hrApproval).

    This would not solve the problem.

    When using the index() function for passing fields in variables to rule inputs, index() returns a copy of the data instead of a reference. Then this exact error happens.
