Script Logic BAS(%VARIABLE%

Hi experts,

The following logic used to work in BPC 7.5 NW but not anymore in BPC 10.0 and I don't get why ...

Structure of my dimension TIME:

ID                    PARENTH1                     NEXT

2013.W45                                               2013.W46

  2013.11.04     2013.W45

  2013.11.05     2013.W45

  2013.11.06     2013.W45

  2013.11.07     2013.W45

  2013.11.08     2013.W45

I enter in the prompt : 2013.W45 as %TIME_SET%

My variable %FCST_WK2% is not recognized (RUN_LOGIC:Member "BAS()" not exist)

// Get the 8 weeks of forecast

*SELECT(%FCST_WK2%,"[NEXT]","TIME","[ID]='%TIME_SET%'")

*SELECT(%FCST_WK3%,"[NEXT]","TIME","[ID]='%FCST_WK2%'")

*SELECT(%FCST_WK4%,"[NEXT]","TIME","[ID]='%FCST_WK3%'")

*SELECT(%FCST_WK5%,"[NEXT]","TIME","[ID]='%FCST_WK4%'")

*SELECT(%FCST_WK6%,"[NEXT]","TIME","[ID]='%FCST_WK5%'")

*SELECT(%FCST_WK7%,"[NEXT]","TIME","[ID]='%FCST_WK6%'")

*SELECT(%FCST_WK8%,"[NEXT]","TIME","[ID]='%FCST_WK7%'")

*XDIM_MEMBERSET PHASE=%PHASE_SET%

*XDIM_MEMBERSET TIME=BAS(%FCST_WK2%)

*XDIM_MEMBERSET ENTITY=%ENTITY_SET%

*XDIM_MEMBERSET RPTCURRENCY=EUR

Any help would be much appreciated.

Thanks

Camille
