Moving data from table1 to table 2.

[aayush_dubey3]

Hello Friends,

I need to move data from table lt_source ( TYPE well defined) to table lt_target. I know the type of lt_target also but the table type of table lt_target gets defined only at runtime.

Also as both tables have some common fields and MOVE-CORRESPONDING cannot be used. Nonetheless the main issue is assigning any value from lt_source to lt_target.

Hi

U need to use the field-symbols, u should store the name of the field it_source in a internal table and use it for the mapping:

LOOP AT IT_SOURCE.
   LOOP AT IT_FIELD.
      ASSIGN COMPONENT IT_FIELD-NAME OF STRUCTURE IT_SOURCE TO <FS_SOURCE>.
      ASSIGN COMPONENT IT_FIELD-NAME OF STRUCTURE IT_TARGET TO <FS_TARGET>.
      IF SY-SUBRC = 0.
         <FS_TARGET> = <FS_SOURCE>.
     ENDIF.
   ENDLOOP.
   APPEND IT_TARGET.
ENDLOOP.

Hello Max,

Thanks for the quick help but i couldn't understand the code provided by you. I do not know usage of FIELD SYBBOLS yet so please find the code snippet attached and guide me further. Also provide the code where you define field symbols

DATA: 
        lt_campaigns TYPE ZTESTCAMPAIGN_TAB,
        ls_campaigns TYPE ZTESTCAMPAIGN.

*............Some code here which fills lt_campaigns table .................

* Things to be done
* MOVE the contents from lt_campaigns to table CT_DB_DATA
* The TYPE of table CT_DB_DATA is assigned only at runtime
* table CT_DB_DATA is transparent table with table type CRMT_MKTPL_WEC which inturn has line type CRMD_MKTPL_WEC
* Also you can assume that ls_campaigns is a different structure from CRMD_MKTPL_WEC with only some fields common.
* All rows are to be copied from lt_campaign to CT_DB_DATA. Some fields are missing but thats OK

Hi

Here u've the solution:

.

 table CT_DB_DATA is transparent table with table type CRMT_MKTPL_WEC which inturn has line type CRMD_MKTPL_WEC.

So u know the CT_DB_DATA is like CRMT_MKTPL_WEC having a like like CRMD_MKTPL_WEC.

So u need to declare a variable like CRMD_MKTPL_WEC and transfer it to CT_DB_DATA

Hi Max,

Thanks for the prompt reply again. I too understand that i need to loop through the table and assign the data to new structure of TYPE CRMD_MKTPL_WEC. Then i should transfer the structure to CT_DB_DATA. But the issue is i do not know how to transfer the data to CT_DB_DATA. What is the syntax for it ? That is the reason i ask question in this forum. Please let me know the code for assignment which is commented in below snippet. Thanks in advance.

DATA: 
        lt_campaigns TYPE ZTESTCAMPAIGN_TAB,
        ls_campaigns TYPE ZTESTCAMPAIGN,
        ls_CT_DB_DATA TYPE CRMD_MKTPL_WEC,
        lt_CT_DB_DATA TYPE CRMT_MKTPL_WEC.
 
*............Some code here which fills lt_campaigns table .................

LOOP AT LT_CAMPAIGNS INTO LS_CAMPAIGNS.
ls_CT_DB_DATA-APPLICATION = LS_CAMPAIGNS-APPLICAION.
LS_CT_DB_DATA-WCMAVERSION = LS_CAMPAIGNS-VERSION_ID.
*ASSIGNMENT CODE HERE
ENDLOOP.
*ADDITIONAL ASSIGNMENT CODE HERE

Hi

U should show the contest where your code need to be placed, I don't know how the table CT_DB_DATA is, i.e. you need to fill it (because it's empty) or u need to change it.

If you need to fill an empty table, u have to fill a workarea and then append it to CT_DB_DATA

.DATA:  lt_campaigns TYPE ZTESTCAMPAIGN_TAB,
             ls_campaigns TYPE ZTESTCAMPAIGN,
             ls_CT_DB_DATA TYPE CRMD_MKTPL_WEC.

LOOP AT LT_CAMPAIGNS INTO LS_CAMPAIGNS.
   MOVE-CORRESPONDING LS_CAMPAIGNS TO LS_CT_DB_DATA.
   APPEND LS_CT_DB_DATA TO  CT_DB_DATA.
ENDLOOP.

By using field symbols i am getting this error now:

" Data objects in Unicode programs cannot be converted"

DATA: 
        lt_campaigns TYPE ZTESTCAMPAIGN_TAB,
        ls_campaigns TYPE ZTESTCAMPAIGN,
        ls_CT_DB_DATA TYPE CRMD_MKTPL_WEC,
        lt_CT_DB_DATA TYPE CRMT_MKTPL_WEC.
 
FIELD-SYMBOLS <fs_ct_db_data> TYPE CRMD_MKTPL_WEC.

ASSIGN LS_CT_DB_DATA TO <FS_CT_DB_DATA>.

*............Some code here which fills lt_campaigns table .................
 
LOOP AT LT_CAMPAIGNS INTO LS_CAMPAIGNS.
ls_CT_DB_DATA-APPLICATION = LS_CAMPAIGNS-APPLICAION.
LS_CT_DB_DATA-WCMAVERSION = LS_CAMPAIGNS-VERSION_ID.
<fs_ct_db_data>-APPLICATION = LS_CAMPAIGNS-APPLICAION.
<fs_ct_db_data>-WCMAVERSION = LS_CAMPAIGNS-VERSION_ID.
APPEND <FS_CT_DB_DATA> TO CT_DB_DATA.
ENDLOOP.

Hi

Can u give me in which context you're working?

You're in a user-exit, BADI......

What's CT_DB_DATA?

Max

[aayush_dubey3]

1. I am in a class method.

2. CT_DB_DATA is a trans table

Hi

U don't need to use the field-symbol, because u know CT_DB_DATA is based on type table CRMT_MKTPL_WEC, and this type is based on CRMD_MKTPL_WEC.

So u need to use a workarea like CRMD_MKTPL_WEC only:

DATA:  lt_campaigns TYPE ZTESTCAMPAIGN_TAB,
            ls_campaigns TYPE ZTESTCAMPAIGN,
            ls_CT_DB_DATA TYPE CRMD_MKTPL_WEC.

Now u need to transfer the data from lt_campaigns to ls_CT_DB_DATA and append it to CT_DB_DATA

LOOP AT LT_CAMPAIGNS INTO LS_CAMPAIGNS.
     ls_CT_DB_DATA-APPLICATION      = LS_CAMPAIGNS-APPLICAION.
     LS_CT_DB_DATA-WCMAVERSION = LS_CAMPAIGNS-VERSION_ID.
    APPEND LS_CT_DB_DATA TO CT_DB_DATA.
ENDLOOP.

The solution above is valid is CT_DB_DATA is define TYPE TABLE

If CT_DB_DATA is defined just like a generic DATA, so TYPE REF TO DATA, in this case u need to use the field-symbols:

DATA:  lt_campaigns TYPE ZTESTCAMPAIGN_TAB,
            ls_campaigns TYPE ZTESTCAMPAIGN,
            ls_CT_DB_DATA TYPE CRMD_MKTPL_WEC.


FIELD-SYMBOLS <CT_DB_DATA_TAB> TYPE TABLE.

ASSIGN CT_DB_DATA->* TO <CT_DB_DATA_TAB>.

LOOP AT LT_CAMPAIGNS INTO LS_CAMPAIGNS.
     ls_CT_DB_DATA-APPLICATION      = LS_CAMPAIGNS-APPLICAION.
     LS_CT_DB_DATA-WCMAVERSION = LS_CAMPAIGNS-VERSION_ID.
    APPEND LS_CT_DB_DATA TO<CT_DB_DATA_TAB>.
ENDLOOP.

How CT_DB_DATA is defined?

Max

[aayush_dubey3]

Dear Max,

As i am syaing from the starting that the TYPE assignment to table CT_DB_DATA happens only at runtime. and yes even if i replace the FIELD-SYMBOL <fs_ct_db_data> with LS_CT_DB_DATA and still it gives the same error.

Data objects in Unicode programs cannot be converted

Hi

Can u say me how CT_DB_DATA is defined in the method?

Max

[aayush_dubey3]

Its a changing parameter of TYPE TABLE CT_DB_DATA

[Former Member]

Ok

And when u've the error:

Data objects in Unicode programs cannot be converted

Max

[aayush_dubey3]

At the append statement in the loop.

APPEND <FS_CT_DB_DATA> TO CT_DB_DATA. or even if i change it to APPEND LS_CT_DB_DATA TO CT_DB_DATA.

[Former Member]

Just last question (I hope)

You obtain the error at runtime or it's a sintax error

Max

[aayush_dubey3]

Runtime error !!!

[Former Member]

Uhm

I think that means the following sentence

table CT_DB_DATA is transparent table with table type CRMT_MKTPL_WEC which inturn has line type CRMD_MKTPL_WEC

is not true.

I've tried a code like your and it works fine, no dump.

Can you check the type of CT_DB_DATA by debug?

Anyway I'll give you a code with field-symbol

Max

[Former Member]

Try to use a code like this:

DATA: LT_CAMPAIGNS TYPE ZTESTCAMPAIGN_TAB,
      LS_CAMPAIGNS TYPE ZTESTCAMPAIGN.

DATA: DFIES_TAB TYPE TABLE OF DFIES,
      DFIES_WA  TYPE  DFIES.

DATA DYN_WA TYPE REF TO DATA.
FIELD-SYMBOLS <WA> TYPE ANY.

FIELD-SYMBOLS: <FS_TARGET> TYPE ANY,
               <FS_SOURCE> TYPE ANY.

* Create the workarea
CREATE DATA DYN_WA LIKE LINE OF CT_DB_DATA.
ASSIGN DYN_WA->* TO <WA>.

CALL FUNCTION 'DDIF_FIELDINFO_GET'
  EXPORTING
    TABNAME   = 'ZTESTCAMPAIGN'
  TABLES
    DFIES_TAB = DFIES_TAB.

LOOP AT LT_CAMPAIGNS INTO LS_CAMPAIGNS.
  CLEAR <WA>.
  LOOP AT DFIES_TAB INTO DFIES_WA.
    ASSIGN COMPONENT DFIES_WA-FIELDNAME OF STRUCTURE LS_CAMPAIGNS TO <FS_SOURCE>.
    ASSIGN COMPONENT DFIES_WA-FIELDNAME OF STRUCTURE <WA>         TO <FS_TARGET>.
    IF SY-SUBRC = 0.
      <FS_TARGET> = <FS_SOURCE>.
    ENDIF.
  ENDLOOP.
  CHACK NOT <WA> IS INITIAL.
  APPEND <WA> TO CT_DB_DATA.
ENDLOOP.
