Lock Object Doubt

Hi I have created 10 Shadow tables and will run the job which updates the data to main data base tables.

So i am creating Lock Objctects for the tables.

Out of 10 tables 8 tables have common key which Business Partner (Primary Key). DO i need to create separate lock object for each of these 8 tables or one lock object is enough.....

In a single lock object you can include the primary and secondary tables.

read the section secondary tables

Dear Chaitanya

Please find the below code

Add the following code in-order to create the table lock. This function module must be called before any

update takes place. If a lock has already been taken out it will display the appropriate message.

CALL FUNCTION 'ENQUEUE_EZ_ZTABLENAME'
      EXPORTING
           mode_ZTABLENAME = 'E'
           mandt              = sy-mandt
           KEYFIELD1           = "Value
           KEYFIELD2           = "Value
           KEYFIELD3           = "Value
                   ...
*         X_KEYFIELD1            = ' '
*         X_KEYFIELD2            = ' '
*         X_KEYFIELD3            = ' '
                   ...
*         _SCOPE             = '2'
*         _WAIT              = ' '
*         _COLLECT           = ' '
*   If exceptions are not used, message is displayed within FM
    EXCEPTIONS
         FOREIGN_LOCK       = 1
         SYSTEM_FAILURE     = 2
         OTHERS             = 3.

  IF sy-subrc <> 0.
*   Retrieve message displayed within Function Module
    message id     sy-msgid
              type   'I'
              number sy-msgno
              with   sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    EXIT.
  ENDIF.

The following code will remove the lock for the specific table entries.

CALL FUNCTION 'DEQUEUE_EZ_ZTABLENAME'
    EXPORTING
         MODE_ZTABLENAME = 'E'
         MANDT              = SY-MANDT
           mandt              = sy-mandt
           KEYFIELD1           = "Value
           KEYFIELD2           = "Value
           KEYFIELD3           = "Value
                   ...
*         X_KEYFIELD1            = ' '
*         X_KEYFIELD2            = ' '
*         X_KEYFIELD3            = ' '
                   ...
*         _SCOPE             = '3'
*         _SYNCHRON          = ' '
*         _COLLECT           = ' '
          .

Thanks
