b) |
Assign the data element S_AGNCYNUM to your new field |
||||
|
ZEMPLOY##-Agency. |
|
|
|
|
c) |
Position the cursor on the field Agency and have the system make a |
||||
|
proposal for the foreign key definition. |
|
|||
d) |
Control the proposal: The check table is SBUSPART. This check table |
||||
|
is not correct since it contains all the business partners of carriers and |
||||
|
not just agencies. |
|
|
|
|
e) |
The correct check table is STRAVELAG, which it contains the agencies |
||||
|
the carriers work with. |
|
|
|
|
f) |
You can improve understanding by looking at the definition of table |
||||
|
STRAVELAG in a second session. Field AGENCYNUM has a foreign |
||||
|
key with check table SBUSPART. This means that table STRAVELAG |
||||
|
is a subset of table SBUSPART. In the foreign key definition for |
||||
|
ZEMPLOY##-Agency, overwrite entry SBUSBART in the input field |
||||
|
Check table with STRAVELAG. |
|
|
||
g) |
Select Copy. The system recognizes the change in the check table |
||||
|
and suggests that it create a proposal. Accept this offer and select the |
||||
|
proposal. The following fields must be assigned: |
||||
|
Check table STRAVELAG |

Unit 4: Input Checks |

Task 4:
Extend the ZDEPMENT## table by one field.
Each department of an airline has a head of department. The assignment between the department and the head of the department should be mapped in the flight model.
1.Enhance table ZDEPMENT## with the Dephead field.
Note: In our model, the personnel number identifies a person. Therefore, the new field to be added to table ZDEPMENT## must contain personnel numbers. The field should also refer to the domain for personnel numbers.
Since the person to be managed in this case has a special role, you should create a new data element and not use the one already created for the personnel number.

Define a suitable foreign key for this field.
Note: Use the two-step domain concept.
a)Go to change mode in the maintenance screen for table ZDEPMENT##. Select the Fields tab page.
b)Choose New rows.
c)Enter the new field DepHead directly following the existing fields by entering a suitable field name in the first column and entering a name for the data element to be created in column Field type.
d)Save the table definition.
e)Select the name of the new data element to be created. Confirm that you want to create a data element.
f)Enter a short text for the data element. Enter the domain name that you already created for the personnel number in field Domain.
g)Select page Field label and enter the corresponding text there.
h)Activate the data element. Go back to the maintenance screen for table ZDEPMENT## by choosing Back.
i)Create the foreign key for the new field in the usual manner. The check table is table ZEMPLOY##.
Note: If you stored this table as a value table for the domain for the personnel number, the system will make this proposal. If not, you have to enter it yourself.
j) You copy the system proposal in the field allocation of the foreign key. k) Enter a short text and determine the semantic attributes as follows:

Task 5:
Create a text table.
1.Create a text table ZDEPMENTT## for the ZDEPMENT## table.

For the field definition, use the data elements (Data type LONG) and
S_TEXT (Data type CHAR, 40)
a)Copy table ZDEPMENT## to table ZDEPMENTT##.
b)Navigate to the field maintenance screen for table ZDEPMENTT##. Delete all the fields that are not key fields. Create the following new fields:
