hi,

You use move command to assing data from one variable to another.

Example.

DATA: var1 TYPE c VAULE 'A',

var2 TYPE c.

MOVE var1 to var2.

You use moe-corresponding to move the data from one structure where the definition of both the strucutre are not same.

Example.

DATA: BEGIN OF lst_struct1,

field1,

field2,

field3,

field4,

END OF lst_struct1.

DATA: BEGIN OF lst_struct2,

field2,

field3,

END OF lst_struct2.

MOVE-CORRESPONDING lst_struct1 TO lst_struct2.

Here, you want to populate the data in lst_struct2 from lst_struct1. But both contains the fields in different order. You can not just do lst_struct2 = lst_struct1. Since fields are out of order, you use MOVE-CORRESPONDING

Hi,

1. Move assigns the value to the specified field.

It is just like a = b.

2. Whereas

3. MOVE-CORRESPONDING STRUCT1 TO STRUCT2

means,

ALL FIELDS HAVING THE SAME NAME,

WILL BECOME EQUAL.

(Rest fields, which do not have same name,

will be ignored)

4. Suppose have a struct1 has 5 fields,

struct 2 has 9 fields,

so instead of giving 5 different lines,

STRUCT2-FIEDL1 = STRUCT1-FIELD1

STRUCT2-FIEDL2 = STRUCT1-FIELD2

STRUCT2-FIEDL3 = STRUCT1-FIELD3

STRUCT2-FIEDL4 = STRUCT1-FIELD4

STRUCT2-FIEDL5 = STRUCT1-FIELD5

We just use MOVE-CORRESPONDING STRUCT1 TO STRUCT2.

Regards,

Priyanka.

Hi,

Move Statement is used to move a variable or a record from one work area to another. it moves data in a order i.e. field by field the order of fields in in both tables should be same otherwise we will get an error.

Example.

DATA: var1 TYPE c VAULE 'A',

var2 TYPE c.

MOVE var1 to var2.

Move Corresponding moves data from one table to another with respect to names of fields. i.e no sequence is maintained . it automatically searches for field names and moves data acoordingly.

Example.

DATA: BEGIN OF lst_struct1,

field1,

field2,

field3,

field4,

END OF lst_struct1.

DATA: BEGIN OF lst_struct2,

field2,

field3,

END OF lst_struct2.

MOVE-CORRESPONDING lst_struct1 TO lst_struct2.

Generally, Move works faster than Move Corresponding.

If u move the order in both tables i.e sequence in both tables r same go for move otherwise use move-corresponding.

Padmam.

MOVE

Assigns values.

Syntax

MOVE <f1> TO <f2>.

Assigns the contents of the data object <f1> to the variable <f2>, with automatic type conversion if necessary. Equivalent to <f2> = <f1>.

MOVE-CORRESPONDING

Assigns values between identically-named components of structures.

Syntax

MOVE-CORRESPONDING <struc1> TO <struc2>.

Moves the contents of the components of structure <struc1> to the components of <struc2> that have identical names.

reward points if it is usefull ..
