Syntax
... dtype | data_element ...
Effect
Types elements or parameters of CDS entities in ABAP CDS. The following is typed:
A typing can be specified either directly with dtype (using a predefined 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.
dtype | Predefined Data Type in ABAP Dictionary |
abap.char( len ) | CHAR with length len |
abap.clnt[(3)] | CLNT |
abap.cuky(5) | CUKY with length 5 |
abap.curr(len,dec) | CURR with length len and with dec decimal places |
abap.dats[(8)] | DATS |
abap.dec(len,dec) | DEC with length len and with dec decimal places |
abap.fltp[(16,16)] | FLTP |
abap.int1[(3)] | INT1 |
abap.int2[(5)] | INT2 |
abap.int4[(10)] | INT4 |
abap.int8[(19)] | INT8 |
abap.lang[(1)] | LANG |
abap.numc( len ) | NUMC with length len |
abap.quan(len,dec) | QUAN with length len and with dec decimal places |
abap.raw(len) | RAW with length len |
abap.sstring(len) | SSTRING with length len |
abap.tims[(6)] | TIMS |
abap.unit(3) | UNIT with length 3 |
In len and dec, specific values must be specified for the length and decimal places (with respect to the relevant generic types). The values specified here in parentheses must be within the value ranges permitted by ABAP Dictionary. The predefined values can be specified for types with fixed lengths and decimal places, but this is not mandatory. For data_element, every ABAP Dictionary data element whose predefined type is listed in the table above can be specified.
Note
Currently no structured or tabular parameters are supported, only elementary data types.
Example
The following CDS view has two input parameters. p_date is typed with the data element DEMODATE and p_num is typed with the predefined data type DEC with both the length and number of decimal places specified.
The program DEMO_CDS_PARAMETER_TYPE accesses the view using the following SELECT statement:
