How To Fix SDDL_PARSER_MSG144 - Invalid value "&1" for annotation "ClientHandling.Type"

SAP Error Message - Details

• Message type: E = Error

• Message class: SDDL_PARSER_MSG - Message Class for DDL Parser

• Message number: 144

• Message text: Invalid value "&1" for annotation "ClientHandling.Type"

What causes this issue?

The values allowed for the annotation <AB>ClientHandling.Type</> with
CDS table functions are:
<AB>#CLIENT_DEPENDENT</> to classify the table function as
client-specific. In this case, the first column of the <AB>Returns</>
list must have the dictionary type <AB>CLNT</>.
<AB>#CLIENT_INDEPENDENT</> to classify the table function as
client-independent.
The value <AB>#INHERITED</> is not allowed for table functions since
these are implemented natively by AMDP and the client handling must be
implemented manually. (<DS:ABEN.CDS_F1_FUNCTION_ANNOTATIONS>CDS Table
Functions</>)

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