to modify table

Modify table itab from wa is not correct

Modify table itab.

is used to change the total internal table from work area containts

and

Modify itab from wa

is used to change the single row in internal table from work area containts

TABLE itab

Effect

The line to be changed is determined by the fact that the content of the table key matches the content of the corresponding components in the wa work area. For tables with a key that is not unique, the first entry that is found is changed.

Example

Conversion of the local currency of an airline to Euro using key access in the scarr_tab internal table.

PARAMETERS p_carrid TYPE scarr-carrid.

DATA scarr_tab TYPE SORTED TABLE OF scarr

WITH UNIQUE KEY carrid.

DATA scarr_wa TYPE scarr.

SELECT *

FROM scarr

INTO TABLE scarr_tab.

READ TABLE scarr_tab INTO scarr_wa

WITH TABLE KEY carrid = p_carrid.

scarr_wa-currcode = 'EUR'.

MODIFY TABLE scarr_tab FROM scarr_wa

TRANSPORTING currcode.

The INDEX addition can also be after FROM wa.

Example

Conversion of the local currency of an airline to Euro in the scarr_tab internal table using index access.

PARAMETERS p_carrid TYPE scarr-carrid.

DATA scarr_tab TYPE SORTED TABLE OF scarr

WITH UNIQUE KEY carrid.

DATA: idx TYPE sy-tabix,

scarr_wa TYPE scarr.

SELECT *

FROM scarr

INTO TABLE scarr_tab.

READ TABLE scarr_tab

WITH TABLE KEY carrid = p_carrid

TRANSPORTING NO FIELDS.

idx = sy-tabix.

scarr_wa-currcode = 'EUR'.

MODIFY scarr_tab INDEX idx FROM scarr_wa

TRANSPORTING currcode.

Check the Help files:

Modify itab from wa

Modify table from wa

Generic change to a single entry in the internal table itab with key. Unlike variant 1, you can use this variant for any table.

Hi,

MODIFY

Change a database table

- MODIFY dbtab.

MODIFY *dbtab.

MODIFY (dbtabname) ... .

- MODIFY dbtab FROM TABLE itab.

MODIFY (dbtabname) FROM TABLE itab.

- MODIFY dbtab VERSION vers.

MODIFY *dbtab VERSION vers.

Change an internal table

- MODIFY itab [FROM wa] [INDEX idx].

[TRANSPORTING f1 ... fn [WHERE cond]].

- MODIFY TABLE itab [FROM wa]

[TRANSPORTING f1 ... fn].

- MODIFY itab [FROM wa]

TRANSPORTING f1 ... fn WHERE cond.

When you use TABLE in MODIFY, then you do not need any LOOP, it will modify all records of table where condition is true.

But when you say MODIFY ITAB, it will just modify taht specific record.

Hope it answers your question.

You can only use this variant with index table (standard or sortedtables).

Modify table itab from wa -

---

Hi Madhavi,

To Change a single Line Using the Table Key use the following statement:

MODIFY TABLE <itab> FROM <wa> [TRANSPORTING <f1> <f 2> ...].

The system searches the internal table for the line whose table key corresponds to the key fields in <wa>.

The TRANSPORTING clause is optional in this statement.

-

---

To change one or more lines using a condition, use the following statement:

MODIFY <itab> FROM <wa> TRANSPORTING <f1> <f 2> ... WHERE <cond>.

This processes all of the lines that meet the logical condition <cond>.

The TRANSPORTING addition is not optional here.Furthermore, you can only modify the key fields of the internal table if it is a standard table.
