ABAP-Logic/Command: Execute An Expression Stored In A Variable

Former Member — Thu, 26 Jan 2006 18:14:26 GMT

Consider the following code - <b>Is it possible to execute the statement/expression stored in variables expression1, expression2 and expression3?</b> The result should be:

sum = 5 , subname = 'First' & i_output should be sorted by lifnr and ebeln.


*---DATA DECLARATIONS
DATA: sum         TYPE i,
      op1         TYPE i,
      op2         TYPE i,

      name        TYPE string,
      subname     TYPE string,
      offset      TYPE i,

      expression1 TYPE string,
      expression2 TYPE string,
      expression3 TYPE string.

DATA: BEGIN OF i_output OCCURS 0,
      lifnr TYPE lfa1-lifnr,
      ebeln TYPE ekko-ebeln,
      ebelp TYPE ekpo-ebelp,
      END OF i_output.

*---BUILD EXPRESSION 1
op1 = 2.
op2 = 3.
expression1 = 'sum = op1 + op2'.

*---BUILD EXPRESSION 2
name   = ' First Name'.
offset = 5.
expression2 = 'subname = name+1(offset)'.

*---POPULATE ITAB I_OUTPUT
MOVE: '111111' TO i_output-lifnr,
      'PO1'    TO i_output-ebeln,
      '010'    TO i_output-ebelp.
APPEND i_output.

MOVE: '111511' TO i_output-lifnr,
      'PO1'    TO i_output-ebeln,
      '020'    TO i_output-ebelp.
APPEND i_output.

MOVE: '111111' TO i_output-lifnr,
      'PO3'    TO i_output-ebeln,
      '010'    TO i_output-ebelp.
APPEND i_output.

MOVE: '114111' TO i_output-lifnr,
      'PO2'    TO i_output-ebeln,
      '010'    TO i_output-ebelp.
APPEND i_output.

MOVE: '111121' TO i_output-lifnr,
      'PO2'    TO i_output-ebeln,
      '020'    TO i_output-ebelp.
APPEND i_output.

CLEAR i_output.

*---BUILD EXPRESSION 3
expression3 = 'sort i_output by lifnr ebeln'.

Thanks in advance!

You can achieve this by generating a subroutine pool dynamically, passing the code lines (expressions) as an internal table. Here is the syntax:

GENERATE SUBROUTINE POOL itab NAME name.

Hope this helps,

But, how can you pass some value/data (say a table which has to be sorted) from the main report to the subroutine-pool?
