How to convert a string to dynamic workarea?

Hi Experts,

I have a string variable whose values is coming dynamically at runtime.

For example v_stg = 'SHP10008006745'.

Here the string contains two values SHP1 and 0008006745. This is in fixed length format.

Here first value is 4 char length and second 10. spaces are replaced by leading zeros. ( we need nor worry about this ).

Similarly this variable can contain 3 values or more because it is dynamically populated.

Now i am creating a workarea dynamically. I am getting the fields for this workarea from a table. So it the above string variable has 2 values then the workarea will have 2 fields. Similarly if the string variable has 3 values then the workarea will have 3 fields.

Now I want to put the value of string variable into this workarea. Based on the length it should automatically assign the values to correct fields of the workarea..

I tried the below code but it does not work and getting the syntax error:

The type of "V_STG" cannot be converted to the type of "STRUC_TAB"

DATA: lo_dyn_type TYPE REF TO cl_abap_structdescr,

struc_tab TYPE REF TO data.

* Create a New Type using the node structure obtained above

lo_dyn_type = cl_abap_structdescr=>create( i_tot_comp_dyn ).

*i_tot_comp_dyn contains the fields required for the dynamic workarea

CREATE DATA struc_tab TYPE HANDLE lo_dyn_type. "<-- struc_tab is my dynamic workarea

struc_tab = v_stg. "<--v_stg is the string variable

Please help

Thanks

Gopal

Hi, you should build an internal table with fields details

DATA: gt_itab TYPE REF TO data

gt_fcat TYPE lvc_t_fcat.

FIELD-SYMBOLS: <fs_fcat> TYPE lvc_s_fcat,

<fs_itab> TYPE STANDARD TABLE,

<fs_wa> TYPE any.

* You can put your fields and their length

APPEND INITIAL LINE TO gt_fcat ASSIGNING <fs_fcat>.

<fs_fcat>-fieldname = 'FIELD01'.

<fs_fcat>-datatype = 'CHAR'.

<fs_fcat>-outputlen = 4.

APPEND INITIAL LINE TO gt_fcat ASSIGNING <fs_fcat>.

<fs_fcat>-fieldname = 'FIELD02'.

<fs_fcat>-datatype = 'CHAR'.

<fs_fcat>-outputlen = 10.

* Create internal table

cl_alv_table_create=>create_dynamic_table(

EXPORTING

it_fieldcatalog = gt_fcat

IMPORTING

ep_table = gt_itab ).

* Assign table

ASSIGN gt_itab->* TO <fs_itab>.

* Create structure

CREATE DATA gs_itab LIKE LINE OF <fs_itab>.

* Assign structure

ASSIGN gs_itab->* TO <fs_wa>.

* Assign values

<fs_wa> = v_stg.

I hope this help you
