Dynamic data: declaration

[Former Member]

Hello,

I am writing a report using different set hierarchy. The set(s) have multiple nodes, and I need an internal table for each of the nodes. If the report is using a set with 10 nodes 10 internal tables are required, if the set has 15 nodes 15 internal tables are needed.

Many times the set hierarchies get re-defined. New nodes get added, old nodes get deleted or reassigned to another hierarchy, etc. So after a while, the two sets may now have 12 nodes and 13 nodes (instead of 10, 15). Correspondingly the data declaration statements in the program have to be changed.

DATA: ITAB01 TYPE STANDARAD TABLE OF <STRUC01>,
            ITAB02 TYPE STANDARD TABLE OF <STRUC02>,
            ......
            ITAB09 TYPE STANDARD TABLE OF <STRUC09>,
            ITAB10 TYPE STANDARD TABLE OF <STRUC10>.

requires to be modified as

DATA: ITAB01 TYPE STANDARAD TABLE OF <STRUC01>,
            ITAB02 TYPE STANDARD TABLE OF <STRUC02>,
            ......
            ITAB09 TYPE STANDARD TABLE OF <STRUC09>,
            ITAB10 TYPE STANDARD TABLE OF <STRUC10>,
            ITAB11 TYPE STANDARAD TABLE OF <STRUC11>,
            ITAB12 TYPE STANDARD TABLE OF <STRUC12>.

Similarly,

DATA: ITAB01 TYPE STANDARAD TABLE OF <STRUC01>,
            ITAB02 TYPE STANDARD TABLE OF <STRUC02>,
            ......
            ITAB14 TYPE STANDARD TABLE OF <STRUC14>,
            ITAB15 TYPE STANDARD TABLE OF <STRUC15>.

requires to be changed to

DATA: ITAB01 TYPE STANDARAD TABLE OF <STRUC01>,
            ITAB02 TYPE STANDARD TABLE OF <STRUC02>,
            ......
            ITAB12 TYPE STANDARD TABLE OF <STRUC12>,
            ITAB13 TYPE STANDARD TABLE OF <STRUC13>.

Is there a way of coding the data declaration dynamically? I know about dynamic programs, but not sure if it is a good option, esp since we have many sets that have more than 100 nodes.

Or can you suggest some other way of writing these reports?

Thank you,

Fred.

Hello Fred,

That's a big task, even if it looks "easy". My first idea is, your request can not be covered by dynamic programming. a) every node has a different structure (I guess), b) the code itself has to be adjusted to the nodes in use as well. I.e. when a dynamic data declaration would be possible, the coding has to adhere the used number of nodes.

My recommendation:

- declare as many standard tables (nodes) as possible

- the code for each node has to be implemented

- define the number of used nodes by a parameter or an interface

Have success,

Heinz

Interesting though tough one.

You can use dynamic internal table creation (and it's work area) using:

CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

Have a read through Rich's Blog - [Dynamic Internal Tables and Structures - ABAP|http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=%28J2EE3417800%29ID1759109750DB10206591421434314571End?blog=/pub/wlg/2071]

Good luck!

Heinz, Aabhas:

Thank you both for your time and suggestions. I could not go ahead with dynmic data declaration, so created deep structures to get what I needed.

Thank you very much again to you both,

Fred.
