Error in ListCube for Remote cube - Error in substep

Question

Hi All,
To start with the details, I've 7.0 version datasource in APO and I've created Remote cube / Virtual provider Based on Data Transfer Process for Direct Access with transformation and some routines in rules.
I've also an "End Routine" as shown below
DATA RSLT_PKG_ROW TYPE  tys_TG_1.
LOOP AT RESULT_PACKAGE INTO RSLT_PKG_ROW.
RSLT_PKG_ROW-/BIC/ZTEST_QTY = 2.
MODIFY RESULT_PACKAGE FROM RSLT_PKG_ROW.
ENDLOOP.
My list cube runs fine and gives the required data without the above end routine for ZTEST_QTY.
when I add the above code in my end routine for populating data for ZTEST_QTY, it is throwing an error message
Error reading the data of InfoProvider
Error in substep.
someone please throw some light on this.
Thanks
KI

Modify your code to this:
CONSTANTS: c_2(1) TYPE n VALUE 2.
LOOP AT result_package
  INTO <result_fields>.
  <result_fields>-/bic/ztest = c_2.
ENDLOOP.
Since the FIELD-SYMBOLS of <result_fields> has been automatically declared in the End Routine, there's no need to define a work area and modify the internal table with the data from the work area.
