Hi Experts,

I have declared as follows:

->DATA: BEGIN OF ACTIVITY,
RF_NUMBER LIKE ZUIHNVLB-RF_NUMBER,
SPACE1(3) TYPE C VALUE ' ',
CREATE_DT LIKE ZUIHNVLB-CREATE_DT,
SPACE2(3) TYPE C VALUE ' ',
CREATE_TM LIKE ZUIHNVLB-CREATE_TM,
SPACE3(3) TYPE C VALUE ' ',
ELPSD_TM LIKE ZUIHNVLB-ELPSD_TM,
SPACE4(3) TYPE C VALUE ' ',
CREATE_ID LIKE ZUIHNVLB-CREATE_ID,
CHANGE_ID LIKE ZUIHNVLB-CHANGE_ID,
END OF ACTIVITY.

->DATA: DESCRIPTION LIKE ZUWB01-WB_DESC.

->LOOP AT RF_TABLE.
ACTIVITY-RF_NUMBER = RF_TABLE-RF_NUMBER.
ACTIVITY-CREATE_DT = RF_TABLE-CREATE_DT.
ACTIVITY-CREATE_TM = RF_TABLE-CREATE_TM.
ACTIVITY-ELPSD_TM = RF_TABLE-ELPSD_TM.
ACTIVITY-CREATE_ID = RF_TABLE-CREATE_ID.
ACTIVITY-CHANGE_ID = RF_TABLE-CHANGE_ID.

MOVE ACTIVITY TO DESCRIPTION. ----->Here iam moving
MOVE RF_TABLE-RF_NUMBER TO KEYINFO.
MOVE ' ' TO DISPLAY_FM.
MOVE VB_OBEX TO EXECUTE_FM.
MOVE INDICATOR_ON TO CHANGE_FLAG.
MOVE INDICATOR_ON TO CREATE_FLAG.

INCLUDE ZUIN0138.
ADD 1 TO SEQ.
APPEND LEVEL_TABLE.
ENDLOOP.

ERROR: "Description" & "Activity" are not mutually convertible in Unicode program.

Please suggest what to do, a fast response would be appreciated.

"One field in ACTIVITY is a decimal type". Yeah - that's why you can't do a straight move. You need to get the decimals into a character format. For that use WRITE ... TO...

Let's say that field is called "AMOUNT".

Create a new structure, ACTIVITY_CHAR with the same field names as ACTIVITY, except for AMOUNT, which you call AMOUNT_CHAR (Type C length 17... or whatever).

MOVE-CORRESPONDING activity TO activity_char.
WRITE activity-amount TO activity_char-amount_char NO-GROUPING RIGHT-JUSTIFIED.
description = activity_char.

Welcome to Unicode world...

  • First check every field is correcly defined (no packed subfield to character subfield or so)
  • Then if some fields are not character type, look at online documentation on ASSIGN CASTING option (or use provided tools such as CL_ABAP_CONTAINER_UTILITIES, actually read the code of this class for some hints)

fields are correctly defined and I cannot change it as it may be used anywhere else.

When using:

call method cl_abap_container_utilities=>read_container_c

exporting

im_container = activity

importing

ex_value = description

exceptions

illegal_parameter_type = 1

others = 2.

it gives error as: "Activity" is not type-compatible with formal parameter "Im_container"

but if I pass any particular field like, activity-rf_number in "Im_conatiner" parameter then its not showing error. But I need all contents of Activity. Please guide for he same.

Try to define a temporary field, 'the container', a character type wide enough , try type STRING. Read source structure into this container and then fill target structure from this container.

Hi Experts,

I would like to mention that :

ELPSD_TM LIKE ZUIHNVLB-ELPSD_TM,

field in ACTIVITY is decimal type.

While Description's field: ZUWB01-WB_DESC is char type.

Moving a packed field to character may give unpredictable results (garbage characters)

Hi Raymond,

Yes that's what I am getting when using

"cl_abap_container_utilities=>fill_container_c". How can I get non-garbage values please suggest.

Thanks.

So MOVE of structure is not a good idea, use some CORRESPONDING statement or even loop on fields indiviaually. (Also it should not work even if not Unicode...)

If the structure contains non-character type field, it will lead to mutually unconvertible error in unicode system. You can use following code to move data from structure to string . 

CALL METHOD cl_abap_container_utilities=>fill_container_c
  EXPORTING
    im_value               = activity
  IMPORTING
    ex_container           = description
  EXCEPTIONS
    illegal_parameter_type = 1
    OTHERS                 = 2.

Hi Monalisa,

I tried your suggestion but the value in 'description' is not coming correct. The decimals value are coming like '#########'. Any suggestion on this like how can I get exact values from activity into description?

Unicode system dont accept that kind of move thats why you have error. Solution is depend on what you want to do.

in your code, i see that you move data from a table to ACTIVITY structure which have all the fields as character type. If data in activity already correct,i think it quite simple by just CONCATENATE all the activity fields into description....

Hi Quynh,

Iam moving data from ACTIVITY to DESCRIPTION. One field in ACTIVITY is a decimal type.

So you may have to use RTTS to check the field type....you may find solution from bellow thread, i dont have time right now to check the solution:

Should be left-justified.
