2.Define the foreign key of the DepCode field in the ZDEPMENTT## table.

Note: The foreign keys for the Client and Carrier fields in the

ZDEPMENTT## table were already correctly defined by copying.

a)First of all, place the cursor on the Department code field in the table ZDEPMENTT##. Choose Goto → Foreign key.

Note: Since you are using the domain of field

ZDEPMENT##-Department code for field

ZDEPMENTT##-Department code, you can use value table

ZDEPMENT## for the foreign key definition.

b) Have the system make a proposal for the foreign key definition. Check the proposal. The following fields must be assigned:

Check table ZDEPMENT##

c) Enter a short text and determine the semantic attributes as follows:

d) Save your foreign key.

3.Define the foreign key of the Language field in the ZDEPMENTT## table.

Note: Since you are using domain SPRAS for field ZDEPMENTT##-Language, you can use value table T002 for the foreign key definition.

→ Foreign key.

b) Have the system make a proposal for the foreign key definition. Check the proposal. The following fields must be assigned:

Check table T002

c) Enter a short text and determine the semantic attributes as follows:

d) Save your foreign key. e) Now activate the table.
