Hi,

NAST is table stores all output types which are triggered from Transaction codes agaist the corresponding object numbers, application, condition types. All those values are automatically stored in NAST and will be avaiable while processing documents. You can check the include RVADTABL.

You can process those messages using RSNAST00 if they flaged for process using schedule program.

Widely you can use NAST table in the print programs of Scripts or Smartforms. Of course, you can use this table in another application for different requirement such IDoc.

Look at the Below to do color for a Single fields in ALV

Look at the below link to do a color for a single line

Hi

1. wot is scalable layer in Sap?

I hope it is application layer of the SAP

2. how to color a single feild in a row in ALVs?

1. add one more field to ur final internal table say COLOR(4)

2. in layout wa_layout-style_fname = 'COLOR'. " if its grid

wa_layout-style_fieldname = 'COLOR'. "if its list

3. read table itab index 3.

itab-color = 'C410'.

modify itab index 3

4. see program SHOWCOLO for all color codes

1. Add a field of data type CHAR(3) to the internal output table.

2. Enter the color code in the appropriate field of the row to be colored in the internal

output table:

Code: 'Cxy'

C = Color (all codes begin with 'C')

x = color number ('1' - '9')

y = highlight ('0' = off, '1' = on)

3. Assign the internal output table color code field name to the IS_LAYOUT importing

structure IS_LAYOUT-INFO_FIELDNAME field and pass this structure in the ALV call

interface.

To enable row coloring, you should add an additional field to your list data table. It should be of character type and length at least 4. This field will contain the color code for the row. So, let’s modify declaration of our list data table “gt_list”.

you should fill the color code to this field. Its format will be the same as explained before at section C.6.3. But how will ALV Grid know that you have loaded the color data for the row to this field. So, you make it know this by passing the name of the field containing color codes to the field “INFO_FNAME” of the layout structure.

e.g.

ps_layout-info_fname = <field_name_containing_color_codes>. “e.g. ‘ROWCOLOR’

You can fill that field anytime during execution. But, of course, due to the flow logic of screens, it will be reflected to your list display as soon as an ALV refresh occurs.

You can color an entire row as described in the next section. However, this method is less time consuming.

Coloring Individual Cells

This is the last point about coloring procedures for the ALV Grid. The procedure is similar to coloring an entire row. However, since an individual cell can be addressed with two parameters we will need something more. What is meant by “more” is a table type structure to be included into the structure of the list data table. It seems strange, because including it will make our list data structure deep. But anyhow ALV Grid control handles this.

The structure that should be included must be of type “LVC_T_SCOL”. If you want to color the entire row, this inner table should contain only one row with field “fname” is set to space, some color value at field “col”, “0” or “1” at fields “int” (intensified) and “inv” (inverse).

If you want to color individual cells, then for each cell column, append a line to this inner table which also contains the column name at field “fname”. It is obvious that you can color an entire column by filling this inner table with a row for that column for each row in the list data table.

3. wot is the use of NAST in smart forms?

When you configure the Output type of any application doc with medium, Partner, messages all those data is stored in NAST table

So to trigger the output for any application doc an entry in NAST is a must

4. how to generate function modules in ALE?

You will create a RFC fun module using SM59 Tcode

INBOUND:

2. Subsystem calls Functional Module EDI_DATA_INCOMING from startRFC program.

3. Data in Control Record is validate against the Partner Profile.

4. IDoc is generated in Database and syntax check is carried out.

5. IDoc file is deleted once file read.

6. Event PROCESSSTATE REACHED is triggered in Idoc Object Workflow.

7. Check for Process Immediately.

If NO

Execute RBDAPP01 Program

Else

Read Process Code from Partner Profile

8. wot is LUW?

The R/3 system is multi user system and many users access the same information at the same time, which is mainly DATA. Consider the case where one user is modifying a record, and second user is trying to delete the same record. If the second user is successful in deleting the record then the first user will face problem for modifying the record that is already deleted. The avoid such situation, R/3 system has provided Logical Unit of Work, which is defined as a locking mechanism to protect transaction integrity. Of course, there are other measures, which ensures data integrity like check table i.e. foreign key relationship. Within SAP system there are three types of transaction and may be distinguished as:

• Database transaction known as LUW. It can be defined as a period in which operation requested must be performed as a unit, i.e. all or nothing operation. At the end of LUW, either of the database changes are committed or rolled back.

• Update transaction or SAP LUW. One SAP LUW can have several databases LUW. So a set of a database is either committed or rolled back. The special ABAP/4 command COMMIT WORK, marks the end of a SAP LUW.

• ABAP/4 transaction. Is made up of a set of related task combined under one transaction code. ABAP/4 transactions are for programming environment, in which ABAP/4 transaction functions like one complete object containing screens, menus and transaction codes.

R/3 system has provided in built locking mechanism, which defines the Logical Unit of Work. Also user can set his own locking mechanism. The LUW starts when a lock entry in the system table is created, and it ends when the lock is released.

To provide the user the facility to communicate with the table in order to modify or delete or insert data, R/3 has provided tool called SCREEN PAINTER. This tool allows you to design screen, process screen through program and update the database table. SAP has provided one and only one way to update the database table, i.e. transaction. Though you can update database table by using open SQL statement through program, SAP usually doesn’t recommend this kind of updating. Many standard transactions are available to update standard table but if the need arises, the developer should be able to develop new transaction, which allows the updating of database tables. This can be achieved by using various components of screen painter.

Hello,

1. The ABAP persistence layer has long provided a stable, powerful, and scalable persistence mechanism that guarantees the

availability and integrity of stored data for your ABAP applications, supports application portability, and provides features like

database abstraction layers and diagnostic tools.
