ISSUE IN PACKAGE TO EXECUTE ALLOCATION

Hi Experts,

I am trying to execute package for allocation by using script logic.

While executing package, it should show me member selection screen for each dimension but it is showing blank page as below:

Clik here to view.

Below is the coding of allocation package script:

PROMPT(SELECTINPUT,,,,"%DL_CATEGORY%DL_CURRENCY%DL_ENTITY%DL_ACCOUNT%UP_ZAIN1%DL_TIME%")

TASK(/CPMB/ALLOCATION_LOGIC,SUSER,%USER%)

TASK(/CPMB/ALLOCATION_LOGIC,SAPPSET,%APPSET%)

TASK(/CPMB/ALLOCATION_LOGIC,SAPP,%APP%)

TASK(/CPMB/ALLOCATION_LOGIC,LOGICFILENAME,ALLOCATION1.LGF)

Please guide where i am mistaken????

Regards,

Zain Bashir
