Error in ER

Hey, looks like the rule mentioned in line 26 is calling another rule within it, namely - cdm2_gettimeentrycdtfielddiff. Open the rule mentioned in line 16 and within that whichever line you are calling rule cdm2_gettimeentrycdtfielddiff, check the and() where you are trying to compare variables. In that one would be an integer and another might be a local variable. Just wrap that local variable in a tointeger(). That should help!
If not advice you to paste the screenshot of the rule cdm2_gettimeentrycdtfielddiff as called from within the rule timeEntryDetailsForActivityHistory!

Hii Harsha,

TimeentryDetailsForActivityHistory:

and  cdm2_gettimeentrycdtfielddiff

In your second rule where you are checking the time entry cdt field difference, add a typecasting logic so that both the values in comparison are of same type.

 eg. value1=value2 can be replaced as cast(typeof(value2),value1)=value2 

In your case value1 i.e. the old record might be null and thus when you are trying to compare that to value 2, having an integer field in it casting error is coming. By using cast() you can make both the values of the same type so that comparison can happen.

Hi Harsha,

Thank you for your response. I am new to Appian Developing so I am trying to understand where i can apply typecasting. could you please help me for this.

Hi Harsha,

Thank you for your response. I am new to Appian Developing so I am trying to understand where i can apply typecasting. could you please help me for this.

Use in line 6 of your rule cdm2_gettimeentrycdtfielddiff where you have condition and(index(oldCDTentry...)=index(newCDTEntry...) 

try replacing that with 

and(cast(typeof(index(newCDTEntry,ri!fields[ri!index],{})),index(oldCDTentry...))=index(newCDTEntry...) 

Hii Harsha,

Is still gives error . I am insert full code below .please help me out.

if(
 and (
    /*To catch lists of values*/
    index(ri!oldTimeEntryCDT, ri!fields[ri!index], {}) =
    index(ri!newTimeEntryCDT, ri!fields[ri!index], {})

            )
          )
        )
      )
    )
  )
)

Just replace the code from line 2-6 as below and see if it resolves the issue. 

and (
    /*To catch lists of values*/
    cast(typeof(index(ri!newTimeEntryCDT, ri!fields[ri!index], {})),
    index(ri!oldTimeEntryCDT, ri!fields[ri!index], {})) =
    index(ri!newTimeEntryCDT, ri!fields[ri!index], {})
  )

Hi Harsha,

Thank you so much for your response. its working fine now.
