do you want the NAME of the variable changed, or do you want to change the contents of your vday variable.

If the latter is the case just concatenate sy-datum+6(2) 'AAA' into vday.

If you want to dynamically create variable names, you will have to use CREATE DATA, or maybe even use the CL_ABAPDESCR classes.

Some examples for Dynamic Creation of Data Objects:

TYPES: BEGIN OF struc,

a TYPE i,

b TYPE c LENGTH 8,

END OF STRUC.

DATA: dref TYPE REF TO DATA,

tname TYPE string,

str TYPE struc,

int TYPE i.

FIELD-SYMBOLS: <int> TYPE i,

<str> TYPE struc,

<f> TYPE any.

dref

CREATE DATA dref TYPE struc.

ASSIGN dref->* TO <str>.

<str>

36 ABC

<str>-a = 36. <str>-b = 'ABC'.

CREATE DATA dref LIKE int.

ASSIGN dref->* TO <int>.

<int>

<int> = 5.

tname = 'SFLIGHT'.

CREATE DATA dref TYPE (tname).

ASSIGN dref->* TO <f>.

<f>

SELECT SINGLE * FROM (tname) INTO <f>.

hi Vandanan,

what sense does it make to have dynamic name of the variable? Have you ever seriously thought on this?
