Data element data type check

[former_member311494]

Hello everyone,

I want to check a data element is a bool type or not,

for example:

     data element: "ZSHOPPING_BOOK_SALED" and it's domain is "BOOLE"( the data type of "BOOLE" is char 1). And now I want to check whether      the "ZSHOPPING_BOOK_SALED" is a bool type or not.

Due to there have no 'bool' data type in ABAP  program, so I want to know is there any standard class methods or function modules that has realized  this function.

Thank you very much.

RTTI?

Hi Matthew,

It's not a RTTI, the data element type is static. thank you very much.

Then the answer to your question question is trivial.

Use values abap_true, abap_false and type abap_bool. You may need to use type pool ABAP, but later kernel versions include this automatically. If you're using web dynpro, then the correct type is wdy_boolean

Hi,

Take data type CHAR with length 1.

and fix value ranges with  'X' and ' '.

You can use standard data element BOOLEAN.

Hi Peng,

You can do the join query on DD01L (Domain Table ) and DD04L(Data Element Table ) table based on the DATA Element ans check the Domain, Lenght and data type.

Based on that, if it's CHAR1 data type or CHAR data type with 1 Lenght. Then it could be the Boolean.

Hi Praveer,

It's a good idea, and very technical. But I think it's a little complicated, however thank you very much.

Well first identify boolean domain -> domain type CHAR length 1, with resticted values list ('X',  ' ') and only those. Then check if the domain  of required field is in the list.
