How To Fix SWDP_WB_TOOL238 - Use WDY_BOOLEAN if &1 is to be used as a Boolean type

SAP Error Message - Details

• Message type: E = Error

• Message class: SWDP_WB_TOOL - Web Dynpro: Messages for Workbench Tools

• Message number: 238

• Message text: Use WDY_BOOLEAN if &1 is to be used as a Boolean type

What causes this issue?

You want to set a type for the attribute &V1&. The type you entered is
defined in the ABAP Dictionary as CHAR 1 and has two fixed values ('X'
and space ). In this way, there is the suspicion that you want to use
this type as a Boolean type.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

In the ABAP language, the Boolean type does not exist. When you execute
a Web Dynpro, however, you need to distinguish between whether the
attribute &V1& is to be treated as a Boolean attribute or not.
Therefore, use the type WDY_BOOLEAN or a type that references the domain
WDY_BOOLEAN.
