This is what I tried to do: Cast (Cast(<timestamp> as abap. DDLS DEMO_CDS_CAST_DATA_ELEMENT The following function module call returns the properties of the view field. These are predefined functions that are realized as scalar functions on the database, This is the blog post series for CDS View and CDS Entities. Learn how to use ABAP CDS views to rearrange database table fields according to application-specific needs from your ABAP source code. The program DEMO_CDS_FLTP_TO_DEC uses SELECT If necessary, a CAST function is added to the generated view in SAP HANA; this ensures that the select item's type in the SAP HANA view is the SAP HANA “type” corresponding to the explicitly specified The data type of the result is defined when the CDS view entity is activated. 3.

Cast expressions Reuse expressions Arithmetic expressions Case expressions Logical expressions Built-in functions Numeric functions String functions Expressions and Functions In a CDS view definition you can use any of the functions and expressions listed in the following example: Learn about CDS view entity conversion functions in ABAP, including special conversions not handled by general CAST expressions. The result of aggregate function I have a STRING field (standard /AIF/ALERTS-KEYFIELDSTRING), but I need it as CHAR in an ABAP CDS view (no table function) for further functions. The cast expression converts the value of the operand operand to the type specified by dtype. dats) as <date> I also thought about Solved: Hi Experts, As I understand its not possible to cast CHAR to DEC based on documentation from SAP. gl/jtFcfy My requirement is to get the difference This example uses a CDS view that pulls data from the BSIK table and demonstrates: Using date functions to calculate differences, add days/months, Hi!
