Cardinality of subnode(Model node)

Hello all,

is it possible to change the cardinality of a sub node...which belongs to a Model node?

For example:

node: Zbapi




outtable <---this table is coming from bapi.....

tables are bi-directional data container....i can pass the data to the bapi using these...

I cannot change the cardinality of the table so i am getting null pointer exception...if i try to set any attribute of outtable....any help on this....will be greatly appreciated....
