Problem with BSEG Cluster Table in Calculation View

Hi,

When I try to create a calculation view type SCRIPT to do a reading on BSEG cluster table, the system answers me that the table does not exist in the schema.

My goal is to make a combined view of multiple tables where the main join is BKPF-> BSEG. As I do?.

Best regards,

/********* Begin Procedure Script ************/

BEGIN

var_out = CE_COLUMN_TABLE("SAPHAD"."BSEG",

["MANDT", "BUKRS", "BELNR", "GJAHR", "BUZEI"]);

END /********* End Procedure Script ************/
