Effect
Types elements or parameters of CDS entities in CDS DDL. The following is typed:
- Elements of CDS entities:
- Elements of the element list element_list in a CDS table function.
- Elements of the element list element_list in a CDS custom entity.
- Elements of the element list element_list of a CDS abstract entity.
- Typed literals in a CDS view entity or a CDS hierarchy.
- Input parameters of CDS entities
- Input parameters of the parameter list parameter_list in a CDS view entity
- Input parameters of the parameter list parameter_list in a CDS table function.
- Input parameters of the parameter list parameter_list in a CDS hierarchy.
- Input parameters of the parameter list parameter_list in an CDS custom entity.
- Input parameters of the parameter list parameter_list in an CDS abstract entity.
- Input parameters of the parameter list parameter_list in a
Typing can be specified either directly with dtype using a built-in data type in ABAP Dictionary, or using the name of a data element data_element. The table below shows the possible options for dtype and their meanings. The last two columns indicate whether the typing is possible for elements or input parameters.
| dtype | Built-In Data Type in ABAP Dictionary | Element | Parameter |
| abap.accp(6) | ACCP (only in a table function) | x | - |
| abap.char( len ) | CHAR with length len | x | x |
| abap.clnt$[(3)$] | CLNT | x | x |
| abap.cuky$[(5)$] | CUKY | x | x |
| abap.curr(len,dec) | CURR with length len and with dec decimal places | x | x |
| abap.d16n$[(16)$] | DECFLOAT16 | x | x |
| abap.d34n$[(34)$] | DECFLOAT34 | x | x |
| abap.datn$[(8)$] | DATN | x | x |
| abap.dats$[(8)$] | DATS | x | x |
| abap.dec(len,dec) | DEC with length len and with dec decimal places | x | x |
| abap.fltp$[(16,16)$] | FLTP | x | x |
| abap.geom_ewkb | GEOM_EWKB | x | - |
| abap.int1$[(3)$] | INT1 | x | x |
| abap.int2$[(5)$] | INT2 | x | x |
| abap.int4$[(10)$] | INT4 | x | x |
| abap.int8$[(19)$] | INT8 | x | x |
| abap.lang$[(1)$] | LANG | x | x |
| abap.numc( len ) | NUMC with length len | x | x |
| abap.quan(len,dec) | QUAN with length len and with dec decimal places | x | x |
| abap.raw(len) | RAW with length len | x | x |
| abap.rawstring | RAWSTRING | x | - |
| abap.sstring(len) | SSTRING with length len | x | x |
| abap.string | STRING | x | - |
| abap.timn$[(6)$] | TIMN | x | x |
| abap.tims$[(6)$] | TIMS | x | x |
| abap.unit$[(2$|3)$] | UNIT with length 2 or 3 (standard length) | x | x |
| abap.utcl$[(27)$] | UTCLONG | x | x |
len and dec must be used to specify values for the length and decimal places of the respective generic types. The values specified here in parentheses must be within the value ranges allowed by ABAP Dictionary. For data types with fixed lengths and decimal places, it is possible, but not mandatory to specify the predefined value for length and decimal places. The exception in this regard is abap.accp: this type has the predefined length of 6, which must always be specified in parentheses. For data_element, every ABAP Dictionary data element whose built-in type is listed in the table above can be specified.
Note
Currently, only elementary data types are supported and no structured or tabular parameters.
Example
The following CDS view entity has two input parameters. p_date is typed with data element DEMODATE and p_num is typed with the built-in data type DEC with a specified length and number of decimal places.
The program DEMO_CDS_PARAMETER_TYPE accesses the view using the following SELECT statement:
SELECT id, col_date, col_num
FROM demo_cds_parameter_type_ve( p_date = @sy-datlo,
p_num = '1.234' )
INTO TABLE @DATA(result).
