ABAP OO: Create data

Former Member — Mon, 11 Sep 2006 09:40:29 GMT

Hello,

I'am experiencing some problems with a Z-Class.

I want to read data from HR-Infotypes. Normaly you can use log. database PNP, macro PROVIDE, GET PERNR and so on.

This you can not use in a class (if there is a way, I would be happy to know how).

So far, I decided to use the function module:

HR_READ_INFOTYPE

So I need a different internal table every time I want to read/check a knew infotype.

Therefore I use the following attributes:

DDIC_TABLENAME;Instance Attribute;Private;Type TABNAME16

ITAB;Instance Attribute;Private;Type Ref To DATA

ITAB should be my dynamic internal table, DDIC_TABLENAME the name of the infotype in use.

Coding in my method:

FIELD-SYMBOLS: <ITAB> TYPE ANY TABLE,

<W_TAB> TYPE ANY.

CREATE DATA: ITAB TYPE (ME->DDIC_TABLENAME).

ASSIGN: ME->ITAB->* TO <ITAB>.

But I'am getting the following dump:

CREATE DATA: The type entered (" ") is not a valid data type.

What's wrong with that?

Regards

Maik

hi,

Change the statement

CREATE DATA: ITAB TYPE (ME->DDIC_TABLENAME).

CREATE DATA: ITAB TYPE <b>ME->(DDIC_TABLENAME)</b>.

Hi,

this is causing the following error during activating:

You cannot use constructor parameters in a dynamic CREATE OBJECT.

table_name = ME->DDIC_TABLENAME.

CREATE DATA itab TYPE STANDARD TABLE OF (table_name).

Hi,

no, it doesn't work: by the way:

System is 4.6C !!!!

CREATE DATA: ITAB TYPE STANDARD TABLE OF (TABLE_NAME).

Table is unknown

As I know, this coding works only with 4.7 and higher.

You're right and so you can create an internal table dunamically only using method CREATE_DYNAMIC_TABLE of cllass CL_ALV_TABLE_CREATE.

Hi,

I tried this way already, but I'am getting a dump too:

GENERATE_SUBPOOL_DIR_FULL

What does this mean?

I used the same coding as I already used in productive programms:

DATA: I_FCAT TYPE LVC_T_FCAT,
ITABREF TYPE REF TO DATA,
WTABREF TYPE REF TO DATA.

FIELD-SYMBOLS: <S> TYPE ANY, "Structure
<T> TYPE STANDARD TABLE, "Table
<FCAT> TYPE LVC_T_FCAT.

FREE: I_FCAT, ITABREF.
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
EXPORTING
I_STRUCTURE_NAME = DDIC_TABLENAME
CHANGING
CT_FIELDCAT = I_FCAT
EXCEPTIONS
INCONSISTENT_INTERFACE = 1
PROGRAM_ERROR = 2
OTHERS = 3.

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
EXPORTING
IT_FIELDCATALOG = I_FCAT
IMPORTING
EP_TABLE = ITABREF.

ASSIGN ITABREF->* TO <T>. "Tab
ASSIGN I_FCAT TO <FCAT>. "Fieldcat
CREATE DATA WTABREF LIKE LINE OF <T>. "Structure
ASSIGN WTABREF->* TO <S>.

If I remember it can generate only certain number of subroutine: from SAP help:

............

Up to 36 temporary subroutine pools can currently be managed for each roll area.

Hi,

yes, you're right - 36 in one session.

So that's the end of it? A rat trap?
