concatenate <f2>........ into <f1>

Hi,

I think the dump may be because you can concatenate only character field.

Check this.

Sri,

first make sure that, all the field symbols are assiagned to some field reference.

I think UR Overwriting a protected field.

The following objects are protected:

- Character or numeric literals,

- Constants (CONSTANTS),

- Function module and method parameters with the type IMPORTING

REFERENCE,

- Untyped field symbols to which a field has not yet been assigned

using ASSIGN,

- TABLES parameters, if the corresponding actual parameter is protected

against changes,

- USING reference parameters and CHANGING parameters in FORMS, if the

actual parameter is protected against changes,

- Field symbols, if the field assigned using ASSIGN is protected against

changes,

- External write access to attributes with the READ-ONLY property.

Write like this :

data : v_10(100) type c.

Assign v_10 to <f1>.

u can use liek tht but before using this the field symbols must be assigned to some variable..otherwise it wil give u dump..

see demo code -

data: name like p0002-vorna,

nachn like p0002-nachn,

f_name(40).

parameter pernr like pernr-pernr.

field-symbols <fs_name> type any.

field-symbols <fs_name1> type any.

field-symbols <fs_name2> type any.

start-of-selection .

assign name to <fs_name>.

assign nachn to <fs_name1>.

select single vorna nachn into (<fs_name>,<fs_name1>) from pa0002

where pernr = pernr.

assign f_name to <fs_name2>.

concatenate <fs_name> <fs_name1> into <fs_name2>.

write: 'Name: ' ,<fs_name2> .

i dont know whether this will solve your problem or not?

first check whether the field symbols are of type c or not?

then concatenate the value to a character field and then assign the value into <f1>.

may be there is some assignment problem to the fieldsymbol but i am not sure.
