Error While Loading data from HFM to Essbase

Question

Hi,
I am trying to load data from a HFM application to Essbase application. The LKM i am using is "HFM Data to SQL" and the IKM is "SQL to Hyperion Essbase(DATA). I am also using couple of mapping expression like {CASEWHEN(HFMDATA."Account" = '3110', 'PL10100', HFMDATA."Account") } , {CASEWHEN(HFMDATA."Period" = 'January', 'Jan', HFMDATA."Period") } etc.
The error i am getting looks like this -
org.apache.bsf.BSFException: exception from Jython:
Traceback (innermost last):
File "<string>", line 23, in ?
com.hyperion.odi.essbase.ODIEssbaseException: Invalid column type specified for Data column [Account]
     at com.hyperion.odi.essbase.ODIEssbaseDataWriter.loadData(Unknown Source)

     at org.python.core.PyInstance.invoke(PyInstance.java)
I am mapping account dimension of HFM to to account dimension of essbase. Both source and target column type is "string" with length 80. Instead of keeping the target "Essbase application", if i keep an Oracle table, columns of which are exactly like essbase application, ODI is loading data perfectly with proper coversion.
Can anyody please help me out.
Many thanks.

Hi John,
Thank you very much for your response. Pasting here the SQl generated at step "8. Integration - Load data into Essbase" in the operator in the description tab, for your perusal -
from com.hyperion.odi.common import ODIConstants
from com.hyperion.odi.connection import HypAppConnectionFactory
from java.lang import Class
from java.lang import Boolean
from java.sql import *
from java.util import HashMap
# Get the select statement on the staging area:
sql= """select CASEWHEN(C3_ACCOUNT = '3110', 'PL10100', C3_ACCOUNT) "Account",CASEWHEN(C4_PERIOD = 'January', 'Jan', C4_PERIOD) "TimePeriod",'HSP_Inputvalue' "HSP_Rates",C8_SCENARIO "Scenario",CASEWHEN(C2_YEAR = '2007', 'FY09', C2_YEAR) "Years",CASEWHEN(C1_CUSTOM1 = '2012', 'Atacand', C1_CUSTOM1) "Product",CASEWHEN(C7_VIEW = 'YTD', 'Input', C7_VIEW) "Version",CASEWHEN(C6_VALUE = 'USD', 'Local', C6_VALUE) "Currency",C9_ENTITY "Entity",C5_DATAVALUE "Data" from "C$_0AZGRP_PLData" where      (1=1) """
srcCx = odiRef.getJDBCConnection("SRC")
stmt = srcCx.createStatement()
srcFetchSize=30
stmt.setFetchSize(srcFetchSize)
rs = stmt.executeQuery(sql)
#load the data
stats = pWriter.loadData(rs)
#close the database result set, connection
rs.close()
stmt.close()
From the SQL, you may find the CASEWHEN expressions. Yes these i have added in the interface mapping section, with the help of ODI expression editor. Following are the expressions i have used, one statement for one mapping each. This is just to make the data of HFM, compatible to Essbase. e.g. - account number in HFM for which i am estracting the data is 3110, but there is no account '3110' in the essbase application, so essbase application wont be able to load the data. To make the HFM data compatible with Essbase, these casewhen statements have been used. I hope its fine to use such statements in mapping.
CASEWHEN(HFMDATA."Year" = '2007', 'FY09', HFMDATA."Year")
CASEWHEN(HFMDATA."View" = 'YTD', 'Input', HFMDATA."View")
CASEWHEN(HFMDATA."Entity" = '100106_LC', '1030GB', HFMDATA."Entity")
CASEWHEN(HFMDATA."Value" = 'USD', 'Local', HFMDATA."Value")
CASEWHEN(HFMDATA."Account" = '3110', 'PL10100', HFMDATA."Account")
CASEWHEN(HFMDATA."Custom1" = '2012', 'Atacand', HFMDATA."Custom1")
CASEWHEN(HFMDATA."Period" = 'January', 'Jan', HFMDATA."Period")
If you can get some idea from the SQL and help me out!
Many thanks.
