Data Manager Package Single Selection

Hi Experts,

I have a data manager package that call a logic.

This is the code of data manager script:

'DEBUG(ON)
PROMPT(SELECTINPUT,,,"Source Category is ACTUAL. Select Destination Category, Entity and Time","%CATEGORY_DIM%%ENTITY_DIM%%TIME_DIM%")

TASK(Execute formulas,USER,%USER%)
TASK(Execute formulas,Environment,%Environment%)
TASK(Execute formulas,Model,%Model%)
TASK(Execute formulas,SELECTION,%SELECTIONFILE%)
TASK(Execute formulas,LOGICFILE,%ModelPath%\..\AdminApp\%Model%\From_IC_to_FIN.lgx)
TASK(Execute formulas,RUNMODE,1)
TASK(Execute formulas,LOGICMODE,1)

It's possible to modify only category prompt in order toprevent the user frommultiselectionof categories ?

Thanks

Samuele
