Hi paluri,

"CHANGE DOCUMENTS" in SAP Terminology

Eg. :

Any change

in the material master will be detected

and a mail will be sent to the concerned

employee.

THIS WILL ALSO DETECT WHICH FILEDS HAVE CHANGED.

IT CAN ALSO GIVE, The Old Value, And The New Value.

2. This Mechanism is called CHANGE DOCUMENTS in

SAP Terminology

3. 2 Fuction Modules are Required.

(They will fetch necessary data from CDHDR,CDPOS)

CHANGEDOCUMENT_READ_HEADERS

CHANGEDOCUMENT_READ_POSITIONS

4. The First FM gives list of all

records ( with change no) which have changed.

5. Loop at the above and the second FM will

provide the details (old-val, new-val) for

each record.

6. While using 1st Fm, give docclass as 'MATERIAL'.

BCOS

the concept of change documents is applicable

to other type of documents also (depends upon

customization)

The tables are

cdhdr (header table)

cdpos (detail table)

HOPE THE ABOVE HELPS.

Kp,

You can activate change documents at the document level. So, when the changes hit the table, the change documents get triggered automatically.

Hi paluri,

1. SCDO

For material master,

the Document type is 'MATERIAL'.

2. For knowing, what to do,

in SCDO,

Find 'MATERIAL' (from below textbox)

3. A new screen will come.

4. In that, all the TABLES (database tables)

are listed which need to be TRACED/MONITOR

for changes.

5. If u have some Z Table,

in SCDO,

click CREATE

6. It will ask for 'Document'

Give some Name and OK.

7. In the detail screen, give u z table.

8. Also see help

Help --> Application help

for reference purpose. it wil help a lot.

Regards,

amit m.

Hi again,

1. Fields - DATA ELEMENTS in table

Make sure that the respectvive data elements

for the fields of your Z Table

have been marked for Change Documents!

2. In SE11

see the fields - data element.

3. See tab - Further Characteristics

4. There is one check box - CHANGE DOCUMENT

Tick this and activate it.

Only those data elements which have

been marked for this purpose,

will be TRACKED for changes.

regards,

amit m.

Hi paluri,

1. Is your problem solved ?

2. I hope u have taken care of the following thins:

a) in scdo, u have pressed the button

'Generate Update pgm.'

b) data element - check box.

3. To view the change documents info,

in scdo,

select your changedocument code,

place the cursor on it,

and press F7.

(becasue in CDHDR, we also require

to know the object class)

so in sell, cdhdr,

just type your name in username,

and see ALL records,

and find out the one of your Z*.

from that check out the object class.

regards,

Hi again,

1. But it is not coming yet

Pls see my previous reply.

2. What is the functin module type update

I suppose u are talking about se37 FM,

radio button 'Update module'.

Well,

This is also nothing but a Function Module,

meant for the purpose of

UPDATING DATABASE TABLES,

in ALL or NOTHING Fashion.

3. Eg.

MIGO Transaction,

Several tables are updated.

They are not updated in the program,

but,

all the SQLS, of these tbles

is PUT / BUNCHED inside a

FM (with update module type).

4. So what happens,

that if there is any error

ALL OR NOTHING happens,

and database integrity is maintained.

5. Moreover, since scren changees

do COMMIT,

it is necessary to BUNCH these

changes in a FM so that everything happesn

in ONE SHOT.

6. Moreover, the UPDATE FM

whenever, it is called,

it LOGS the request and its details,

in a special table.

5. Afterwards, when the main program calls COMMIT,

it carrys out the request of updating

the database tables.
