An error occurs when trying to exit from ALV report

[stefan_kolev4]

Hi,

I have a report which imports and display in ALV data from an excel file. Unfortunately when I'm trying to exit I receive an error as I copied below.

Runtime Errors MOVE_TO_LIT_NOTALLOWED_NODATA

Date and Time 17.10.2008 08:39:18

Short text

Error at assignment: Overwritten protected field.

What happened?

Error in the ABAP Application Program

The current ABAP program "SAPLSLVC_FULLSCREEN" had to be terminated because it

has

come across a statement that unfortunately cannot be executed.

Error analysis

A new value is to be assigned to the field "<L_BOX>", although this field is

entirely or partly protected against changes.

The following are protected against changes:

- Character literals or numeric literals

- Constants (CONSTANTS)

- Parameters of the category IMPORTING REFERENCE for functions and

methods

- Untyped field symbols not yet assigned a field using ASSIGN

- TABLES parameters if the actual parameter is protected against changes

- USING reference parameters and CHANGING parameters for FORMs, if the

actual parameter is protected against changes and

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

protected (or partially protected, e.g. key components of an internal

table with the type SORTED or HASHED TABLE) against changes

- Accesses using references, if the field bound to the reference is

protected (or partially protected) against changes

- External write accesses to READ-ONLY attributes,

- Content of a shared object area instance accessed using a shared lock

(ATTACH_FOR_READ).

Trigger Location of Runtime Error

How can I solve the problem ?

Hi ,

Please check the GUI status you are using for the ALV.

Looking at the code what i feel is that the error occurs when the user action is the code &SAL' or '&ALL'.

Please put a break point at the statement and see why is the error occurring

Regards,

Arun

Thank you Arun, but when I've commented import parameter " i_callback_pf_status_set = 'SET_PF_STATUS' " the error still appear.

Hi Stefan ,

If that is the case then i would suggest you to please check the field catalog again , because some times because of some wrong entries in the catalog the ALV generates some errors.

I have had just now the problem: probably you have specified the fields box_tabname and box_fieldname of structure slis_layout_alv. If 46c wasn't necessary specified these as fields in data internal structure passed to ALV standard function ( t_outtab and it_fieldcat), in Ecc6 you need to declare them. So if they aren't necessaries for the user's work clear the two fields in slis_layout_alv, otherwise declare.

Thanks a lot for this help.

Cleaning slis_layout_alv-box_fieldname solved the issue.
