Using Check table after dynamic selection

[Former Member]

Hi Friends,

DB A006 is described dynamically using concatinate.

Concatinate 'var1' 'var2' into var3 --> result = A006

1.

I want to describe var3 using the method cl_abap_typedescr=>describe_by_data

Q:

Is this possible. If yes, please how??

2.

I then want to access the compoment field of var3. Example A003-KSCHA

Q:

Is this possible. If yes, please how??

3.

If point 2 above is successful, I want to access the Check table of A003-KSCHA (T681A)

Q:

Is this possible. If yes, please how??

Ys,

Hi,

If A006 is a table name then you can find the it's field information using fm DDIF_FIELDINFO_GET, you also get the check table name for every field from the o/p of the function module.

Hello,

Answer to all your question is YES! Check the code below for the details:

PARAMETERS: p_table TYPE tabname OBLIGATORY.

DATA: lcl_struc TYPE REF TO cl_abap_structdescr,
      it_ddic_detail TYPE ddfields,
      wa_ddic_detail TYPE dfies.

lcl_struc ?= cl_abap_typedescr=>describe_by_name( p_table ).

* Check if the structure is DDIC
CHECK lcl_struc->is_ddic_type( ) = 'X'.
it_ddic_detail = lcl_struc->get_ddic_field_list( ).

READ TABLE it_ddic_detail INTO wa_ddic_detail
WITH KEY fieldname = 'KSCHL'.
CHECK sy-subrc = 0.
WRITE: 'Check table for KSCHL:', 30 wa_ddic_detail-checktable.

Thank u all for your suggestion, but i have solved this problem myself.

How?

1. I selected all fields of database DD03L Dynamically...

Select * from dd03l into table itab where tabname = my_dynamic_table_value

2. Loop over ITAB into WA_ITAB

§. Dynamic selection of CHECKTABLE...

DATA: line(72) TYPE c,

list LIKE TABLE OF line .

Select (gs_filedname_of_check_table) into table LIST from (my_dynamic_checktable_value)
