... TIMS_IS_VALID(time) ...

Effect

In a CDS view entity, the function TIMS_IS_VALID determines whether the positional parameter time contains a valid time in the format HHMMSS. The actual parameter must have the built-in data type TIMS. time can be specified as literal, field of a data source, parameter, path expression, reuse expression using $projection, or built-in function. 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.

Note

It is not currently possible to access the current system time directly in a CDS view entity. Instead, a CDS view entity 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.

Example

The following CDS view entity demonstrates how to use the time function TIMS_IS_VALID. The program DEMO_CDS_TIME_FUNC_VE uses SELECT to access the view. You can assign any value to the column TIMS1 of the DDIC database table DEMO_EXPRESSIONS.
