Problem with NETPR field in BDC

Hi,

1.)I am creating BDC for ME11...in which i need to pass NETPR ( length = 11 dec pt. = 2 ) field.

In the BDc program in th internal table i have declared the field as:

NETPR type EINE-NETPR.

In the text file i m passing the value 100.00,

but when i m processing the sessions its givin an error sayin 'Input field has length more than screen field'.

Why so....

2.)When i m changin its type to NETPR(11) ie char its workin just fine.....

3.) when field has length = 11 an decimal pt = 2.. what max length value field can take..

is it 12345678912.00 or 123456789.00

pls help.
