function in report do not works with ` `

Applications Grid / Reports
#1

i created a report with this SQL in version 7.00001 and this worked fine.

SELECT f_get_ccp_nmrodoc(ccp_cdgo,tdo_cdgo) as numero_factura, ccp.ccp_nmro as ccp_ccp_nmro
from ccp_cntas_cyp ccp, ter_trcro ter
where ccp.ter_cdgo = ter.ter_cdgo and ccp.neg_cdgo = 1 and ccp_procsdo = ‘S’ and ccp_actvo = ‘S’ and ccp.ccp_tpocnta = ‘CXC’

now, i modified my report and SC set automatically to my function:

SELECT f_get_ccp_nmrodoc(ccp_cdgo,tdo_cdgo) as numero_factura, ccp.ccp_nmro as ccp_ccp_nmro, ccp_newfield as newfield
from ccp_cntas_cyp ccp, ter_trcro ter
where ccp.ter_cdgo = ter.ter_cdgo and ccp.neg_cdgo = 1 and ccp_procsdo = ‘S’ and ccp_actvo = ‘S’ and ccp.ccp_tpocnta = ‘CXC’

and with these do not works!

how can i fix this bug?

#2

i created new report with the SQL and works fine.
i think that this bug is when i modify a report.

#3

i find out that the error is when the function has 2 or more parameters. with one it works fine.
