In the ABAP dictionary the same domain is required for hte check field and the referenced field of the check table so that you do not compare fields with different data types and field lenghts.Domain equality is essential. Different data elements can be used but they must refer to the same ____
Explanation
In the ABAP dictionary, when using a check field and a referenced field from a check table, it is important to have the same domain for both fields. This ensures that the fields being compared have the same data type and field length. While different data elements can be used, they must still refer to the same domain in order to maintain consistency and accuracy in the comparison.Rate this question:

A domain describes the value range of a field by specifying its d t and f l.
Explanation
The given statement suggests that a domain describes the value range of a field by specifying its data type and field length. In other words, a domain defines the type of data that can be stored in a field and the maximum length or size of that field. By specifying the data type, the domain ensures that only valid data of the specified type can be stored in the field, while the field length determines the maximum number of characters or digits that can be stored in the field.Rate this question:

A foreign key links two tables. The check table is the table whose fields are checked. The check table is also called the r t. The field of the foreign key table to be checked is called the c f.
Explanation
The given answer is a list of terms related to the concept of a foreign key in a database. The "reference table" refers to the table that contains the primary key being referenced by the foreign key. The "check field" is the field in the foreign key table that is being compared to the primary key in the reference table. Overall, the answer provides a concise summary of the key components involved in establishing a relationship between tables using a foreign key.Rate this question:

The requirement for domain equality is only valid for the check field, for all other foreign key fields it is sufficient if the d t and the f l are equal
Explanation
The requirement for domain equality is only valid for the check field, for all other foreign key fields it is sufficient if the data type and the field length are equal.Rate this question:

Specifying fixed values causes the value range of the domain to be r b t v
Explanation
When specifying fixed values, the value range of the domain is limited or restricted by these values. This means that any input or variable within the domain must fall within the specified values. It implies that the values outside of this range are not valid or applicable.Rate this question:

Fixed values are immediately used as c v in screen entries and there is also f h.
Explanation
The given answer suggests that the "check values f4 help" option should be used to verify or access the fixed values (c v) and screen entries (f h) immediately. This implies that by selecting the "check values f4 help" option, users can ensure that the entered values are correct and can also view additional information or suggestions related to those values.Rate this question:

Fxed values can be listed i or defined as an i

In contrast to fixed values specifying value table does not provde c or f h.
Explanation
The given answer suggests that in contrast to fixed values, specifying a value table does not provide information about "c" or "f h". Instead, it recommends checking the "f4 help" for further assistance or clarification. The explanation implies that the "f4 help" feature may provide additional guidance or options related to the values in question.Rate this question:

A value table only becomes a check table when
-
It is activated in the data dictionary
-
A foregign key is defined
Correct Answer
A. A foregign key is definedExplanation
When a foreign key is defined in a value table, it becomes a check table. This means that the value table is used to validate the values entered in another table. The foreign key establishes a relationship between the value table and the table where it is used as a check table. This relationship ensures that only valid values from the value table can be entered in the corresponding field of the other table. Therefore, the presence of a foreign key is what transforms a value table into a check table.Rate this question:

True or falseThe requirement for domain equality is only valid for the check field,
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true. The requirement for domain equality is only valid for the check field, meaning that it is necessary for the check field to have the same domain as the other fields being compared. This ensures that the values being compared are of the same type and can be properly evaluated for equality.Rate this question:
