use of @dpvalue variable after migration form DeskI 3.1 to WEBI 4.1

Hi all,

I have converted a report DeskI from BOXI 3.1 to Webi 4.1 with Report Conversion Tool.

The conversion is OK but when I refresh the report the result is different .

In the query of report Deski is present the variable @dpvalue in the where condition

(   @dpvalues('( RTRIM(RETEAM.NODO.COD_ORG) ) || '-' || ( RETEAM.NODO.SER_NODO) || '-' || ( RETEAM.NODO.NUM_NODO)',9,242)@dpend)

but in the Webi is trasformed in 

  ( RTRIM(RETEAM.NODO.COD_ORG) ) || '-' || ( RETEAM.NODO.SER_NODO) || '-' || ( RETEAM.NODO.NUM_NODO)  IN  @dpvalue('A', DP0.DOe1e)

The effect in the data is that is present the error #MULTIVALUE

how to correct the variable to obtain the same data?

Bye
