Where can i find out cast data type information of cast function in the CDS view ?

[jungwoo_han]

Dear CDS experts and developers.

For example, We can see lot of cast functions and data types on CDS view.

....

cast(acdoca.rldnr as fins_ledger_pers) as rldnr_pers,

cast(acdoca.rbukrs as fis_bukrs) as rbukrs,

...

The "fins_ledger_pers" and "fis_bukrs" are used as a cast data type under cast function.

How and where can i figure out these cast data type ?

I've seen CDS manual and various documents however I couldn't find it anywhere.

thanks and best regards,

Jungwoo.

It seem's that you havn't seen the SAP documentation itself:

"The following can be specified for dtype:

◾Any data element ...

◾A built-in data type from ABAP Dictionary ..."
