Former Member — Thu, 25 Jun 2009 16:00:39 GMT

Hi,

i try to do assign component like that and i get this dump ,any idea why?

after i doing the assign component commend in the line

<date> = sy-datum.

i get the dump :

field symbols: <date>  type sy-datum.



  ASSIGN is_bound_object TO <ls_object>.
  ASSIGN COMPONENT 'DATE' OF STRUCTURE <ls_obt> TO <date>.
  <date> =  sy-datum.

the error:

The following are protected from change:

- Character literals or numerical literals.

- CONSTANTS.

- Parameters of the category IMPORTING REFERENCE in functions and

methods.

- untyped field symbols, that have not been assigned a field using

ASSIGN.

- TABLES parameters, if the actual parameter is protected against

changes.

- USING reference parameters and CHANGING parameters in FORMs,

if the actual parameter is protected against changes.

- Access using field symbols if the field assigned using ASSIGN is

partly or completely protected (for example key components of in

table of the type SORTED or HASHED TABLE).

Hi,

Are you trying to change some importing parameters?

Is the type of field 'DATE' OF STRUCTURE <ls_obt> same as sy-datum?

Hi Nina ,

Are you tried to change field symbols: <date> type sy-datum to type any ?

Because, <date> may receive any value and not just datum.

Try..

WRITE sy-datum TO <date>.

The dump is very informative. Are you trying to change some parameter? What is is_bound_object? have you checked date is being assigned to the field symbol?

It is working because sy-datum can be changed, so there is no problem with the assign.

Your code can present several problems.

First, what is is_bound_object? The dump says it clear, if it is an importing parameter, you can't change it. If you want to change the value of the variable in the calling program, then that's a different story.

Second, the second assign returns sy-subrc = 0? If it doesn't the structure has no 'DATE' component and you are getting the dump because of that

HI ,

is_bnd_obj it's parameters that i get in the import ,

and i want to update it why i can to that ?

the Sy-subrc returen 0.

i have mistake when i copy it ,it should be:

ASSIGN is_bnd_obj TO <ls_obt>.

ASSIGN COMPONENT 'DATE' OF STRUCTURE <ls_obt> TO <date>.

<date> = sy-datum.

HI,

If it is an importing parameter it cannot be changed.

HI Ankur ,

There is no way to overcome/Bypass this issue, the thing is in that the import parameter is type any ,i.e. can get any type of structure and i need to modify it.

Best regards

Can you change it from an IMPORTING parameter to CHANGING?

No, you can also define a local variable and copy the IMPORTING parameter to it (so long as you only need this value in this form or FM).
