Groovy: Essbase Error(0) Invalid member name

Hi all,

I am trying to retrieve the date from a combination using DataGridDefinitionBuilder and extract year, month and day from it.

The approach might be a bit long but I am converting the data retrieved to long followed by string.

But, when I am using substring() function to extract year, month and day, the calculation manager is throwing the below error. I haven't written any Essbase Calculation in the groovy script.

The following the full code for your reference:

def valuestartdate
def strstartdate

def Strstartdateyear
def Strstartdatemonth
def Strstartdateday
long longVar

Cube cube = operation.application.getCube("Plan1")

DataGridDefinitionBuilder builder = cube.dataGridDefinitionBuilder()
