READ is used to read the contents in an internal Table

READ table ITAB index 2

MOVE is used to move the data from one field to another field or within a internal table

Move itab-f1 to ITAB1-f2.

move date1 to date2.

READ is used to read the records in the internal Table.

MOVE is used to move the value from one field/Staructur/Int table to another.

Read command will read the contents of a table. You can read an internal table by specifying key fields. Or if you want to read a particular row in an internal table you can mention that row index.

Ex. of Read statement.

loop at itab.

Read table itab1 with key lifnr = itab-lifnr.

endloop.

Read table itab index 1. -Reading the first row of the internal table.

Move statement is used to move the contents of a field to another field.

Ex.

Data: m1 type i,

m2 type i.

m1 = 90.

Move m1 to m2.

Now the contents of m1 i.e are copied to m2.

hi,

syntax.

read table itab_x with key <fieldname > = itab.

the above statement just read the first row from internal table with the given condition.

move itab_x-<fieldname> to itab-<fieldname>.

the above statement is used when we need to move fields from one internal table to another internal table.

Hi Harita,

1. In Report why we will use Read Statement.

2. In Report before using Read Statement why we will go for sorting?
