Accessing an included structure .

[Former Member]

I have an internal table that has an included structure. This structure has 45 fields of the same type. I need to get a specific entry from this table and then read, and eventually modify, a field in the included structure. I assumed I could read it like the code below but it gives me a syntax error. wa_detail is a work area and days is the structure with index_days being the index.

FORM updatedaystructure .

DATA: temp_quantity TYPE i.

temp_quantity = wa_detail-days INDEX index_day.

ENDFORM.

Try:

FORM updatedaystructure .
DATA: temp_quantity TYPE i.
Read table detail into wa_details index index_day.
temp_quantity = wa_detail-days.

ENDFORM

You have to replace "detail" with the name of your actual table.

Rob, thanks for the reply. I need the index to act on the structure (days) not the table. This is why I'm having trouble. I may be wrong but I believe your example is having the index to act on the table not the structure

EDIT: The syntax error I get is "Arithmetic operations are only intended for operands that can be converted to numbers."

Yes - that's right. I think you can probably do what you want using field symbols.

I've tried several things, the following be the best in my uninformed opinion, but I keep getting the same syntax error.

FORM updatedaystructure .
  DATA: temp_quantity TYPE i,
        temp_day TYPE i.
  FIELD-SYMBOLS <field> TYPE z45days.
  ASSIGN wa_detail-days TO <field> CASTING..

  temp_day = <field> INDEX index_day.

ENDFORM.

I have tried the following and it tells me that wa_details-days is not defined but it is. All I need to do is add a number to the entry in wa_detail-days (index index_day).

wa_detail-days index index_day = wa_detail-days index index_day + wa_detail_temp-erfmg.

Any help would be appreciated!

Hi,

Try using this code

***********************************************************************************************

***********************************************************************************************

FORM updatedaystructure .

DATA: temp_quantity TYPE i,
         wa_days like days.      "this is type of structure DAYS

FIELD-SYMBOLS: <field> TYPE z45days. " type of "field in structure DAYS"

**index1 is used to read table entry where you want to update DAYS
Read table detail into wa_details index index1 .  ( this is not index_days)  

wa_days = wa_index-days.

ASSING COMPONENT index_days OF STRUCTURE wa_days TO <field>.
ENDFORM

***********************************************************************************************

***********************************************************************************************

This way you will get the content of field in DAYS.

If you can give me the structure of your table, structure of DAYS ( give me the field type since all fields are same) and what exactly you are trying to achieve, i might be able to help you.

RS, thanks for the reply. Below is the structure of the table.

TYPES: BEGIN OF ty_detail,
          matnr TYPE mseg-matnr,  "Mat. #
          bwart TYPE mseg-bwart,  "Movement Type
          erfme TYPE mseg-erfme,  "Unit of entry
          erfmg TYPE mseg-erfmg,  "Quantity in unit of entry
          werks TYPE mseg-werks,  "Plant #
          maktl TYPE mara-matkl,  "Mat Group
          mtart TYPE mara-mtart,  "Mat Type
          maktx TYPE makt-maktx,  "Mat Description
          days TYPE z45days,
      END OF ty_detail.

Days just holds 45 fields of type QUAN. Ultimately I am trying to add an integer to a component in the structure (keep a running tally). When I enter this form I already have the work area for the table loaded with the right entry (wa_detail) and I also have the index of the work area (index_table) (I stored the index in case I couldn't use the work area). I also have the index of the needed component in the structure (the component that needs to be updated) stored in index_day.

Any help you can give me would be more than appreciated!

Regards,

Davis
