what is a dynamic field and what is its use?

Hi,

You can assign value to the field at runtime

For ex:

DATA: STR_DYNAMIC type string.

FIELD-SYMBOLS <FS_DYNAMIC> type any.

STR_DYNAMIC = 'st_vbak-vbeln'.

Here the value in STR_DYNAMIC is actually the fieldname whose value you want to read.

code

ASSIGN (STR_DYNAMIC) TO <FS_DYNAMIC>.

the above step takes the fieldname and then assigns the value stored in that fieldname to the field symbol

Generally Assign statements can give Short Dumps if the assignment is not possible. So recommended approach is check for sy-subrc.

Write the below code in If condition.

code

IF sy-subrc eq 0.

<FS_DYNAMIC> = field_value. "or your value

UNASSIGN <FS_DYNAMIC>. "This step is required to free up assignment

ENDIF.

[/code]

Hope this helps.

santosh,

Dynamic field means:

In certain conditions you don't know what is the data

type of input fileds.

To catch those values general data variable declaration will not work .For those you need to declare Fields symbles.

EX;

DATA: STR_DYNAMIC type string.

FIELD-SYMBOLS <FS_DYNAMIC> type any.

STR_DYNAMIC = 'st_vbak-vbeln'.

ASSIGN (STR_DYNAMIC) TO <FS_DYNAMIC>.

Don't forget to reward if useful.....
