Needed Details on GETTAB,SETTAB,CHETAB,RESTAB.

Question

Can anyone clearly state with an example of GETTAB,SETTAB,CHETAB,RESTAB in ECATT and the practical usage of where to use it.
I have referred help.sap.com.Needed some more information.
Thanks in advance.

Hi vishwakarma
<b>GETTAB</b>
Syntax :
GETTAB ( <table> , <command interface> ).
GETTAB ( <table> , <command interface> , <target system> ).
1.  The GETTAB command reads a record from a database table, and assigns the values from the record to the corresponding fields of a command interface (the command interface has the same structure as the table).
2.  You specify the values of the key fields in the command interface. You do not have to specify the complete key. Enter an asterisk in each key field for which you do not assign a value.
3.  If the complete key is not specified, several records might satisfy the selection criteria. GETTAB reads the first record found that satisfies the selection criteria.
4.  You can specify which system the database table is in. If you specify a target system, the test script or the test configuration must have an appropriate system data container.
Procedure
1.  In the command editor, enter GETTAB ( <table> , <command interface> ).
2.  Double-click <command interface>.
3.  The command interface appears in the structure editor.
4.  In the structure editor, enter values in the key fields. Make sure that each of the key fields is filled with a fixed value, a parameter, or an asterisk.
<b>CHETAB</b>
Syntax:
CHETAB ( <table> , <command interface> ).
CHETAB ( <table> , <command interface> , <target system> ).
1.  The CHETAB command compares field values in a database table with values that you specify in the command interface (the command interface has the same structure as the table). You can use it to check:
2.  Database updates after transactions
Whether a particular table entry exists
Customizing table entries
3.  You specify the values of the fields in the command interface. You are not restricted to using the key fields. You do not have to specify the complete key. However, you should not leave a key field empty: enter an asterisk in each key field for which you do not assign a value.
4.  If no record that satisfies the search criteria is found, an error message is entered in the log.
5.  If one or more records are found, the check is entered in the log as successful.
6.  You can specify which system the database table is in. If you specify a target system, the test script or the test configuration must have an appropriate system data container.
Procedure
1.  In the command editor, enter CHETAB ( <table> , <command interface> ).
2.  Double-click <command interface>.
The command interface appears in the structure editor.
3.  In the structure editor, enter the values that you want to check. Make sure that each of the key fields is filled with a value, parameter, or an asterisk.
<b>SETTAB</b>
Syntax :
SETTAB ( <customizing table> , <command interface> ).
SETTAB ( <customizing table> , <command interface> , <target system> ).
1.  SETTAB changes a customizing table (other databank tables cannot be affected). SETTAB can modify entries or create new ones.
2.  The original values of the changed entries are stored in an internal backup table. The customizing table can be restored to its original state, or confirmed in its changed state, by the RESTAB command. eCATT executes RESTAB ( RESET ) at the end of any script in which a SETTAB has been executed. You do not need to enter this command explicitly at the end of a test script.
3.  You specify the values of the fields in the command interface. You do not have to specify the complete key. eCATT uses the appropriate initial values for key fields in which no values have been entered.
Procedure
1.  In the command editor, enter SETTAB ( < customizing table> , <command interface> )
Double-click <command interface>.
The command interface appears in the structure editor.
2.  In the structure editor, enter the values for the fields.
Example
SETTAB ( T619F , T691F_1 ).
<b>RESTAB</b>
Syntax:
RESTAB ( RESET ).
RESTAB ( <customizing table> ).
RESTAB ( SET ).
1.  RESTAB only affects Customizing tables that have been changed by SETTAB earlier in the execution of the test script.
2.  The RESET option removes the changes made by SETTAB. All the tables will be reset.
3.  If you specify a table, only that table will be reset by RESTAB.
4.  The SET option makes the changes made by SETTAB permanent: these changes will not be affected by a further RESTAB.
5.  eCATT executes RESTAB ( RESET ) at the end of any script in which a SETTAB has been executed. You do not need to enter this command explicitly at the end of a test script.
Example
SETTAB ( T691F , T691F_1 ).
RESTAB ( T691F ).
Dont forget give pts if it helps ;>)
