CalcEngineException error when clicked on REFRESH button on Forecast Approval workbook in RDF

Hi Experts,

I am getting below error when click on REFRESH button on Forcast Approval workbook. I am using 13.2.2.26 Build.

"CalcEngineException: The refresh rule group FAP_REFRESH (DOWtemp = if(current <today, DoWFinal,0)) is not consistent with the current rule group."

Although, this rule is exists in configuration and even under the rulesets folder also the rule is propagated properly (/rpas_data/rdf/configuration/RDFcfg/RDF/rulesets/FAP). Like below.

 <attribute name="name">
        <value>E0</value>
      </attribute>
      <attribute name="formula">
        <value>DOWtemp = if(current &lt; today, DoWFinal, 0)</value>
      </attribute>

Can anybody help on this?

Thanks,
