ABAP_SYNTAX ... TIMS_IS_VALID(time) ...
ABAP_VARIANTS: 1 ... TIMS_IS_VALID(time)
What does it do? In a ABAP_CDS_V1_VIEW , these functions execute operations with arguments of the built-in data type TIMS. The functions have positional parameters to which actual parameters need to be assigned when called. There are currently no optional parameters. Suitable fields of a data source, literals, parameters, path expressions, built-in functions, or expressions can all be specified as actual parameters. If an actual parameter contains the null value, every function except TIMS_IS_VALID returns a null value.
Latest notes: It is not currently possible to access the current system time directly in a CDS view. Instead, a CDS view can be given an appropriate input parameter. The special annotation @Environment.systemField makes it possible to pass the value of the ABAP system field sy-uzeit to this parameter. NON_V5_HINTS ABAP_HINT_END
ABAP_VARIANT_1 ... TIMS_IS_VALID(time)
What does it do? The function TIMS_IS_VALID determines whether time (if specified) contains a valid time in the format HHMMSS. The actual parameter must have the built-in data type TIMS. The result has the data type INT4. A valid date produces the value 1 and all other input values (including the null value) produce the value 0.
ABAP_EXAMPLE_VX5 The following CDS view applies time functions in the SELECT list to columns of the DDIC database table DEMO_EXPRESSIONS. The class CL_DEMO_CDS_TIME_FUNCTIONS uses SELECT to access the view. The column TIMS1 of the DDIC database table can be given any values. DDLS DEMO_CDS_TIME_FUNCTIONS ABAP_EXAMPLE_END
