Error during generation of smartform Z0001

Question

Hy guys,
First: I'm working with Netweaver Trial version 7.2 64 bits in Windows 7 HP.
When i try generate any smartform (standard or custom), always appears this error "Error during generation of form ..." [name of smartform]. In ST22 i can see that, the error occurs in function "CALL_FUNCTION_SIGNON_INCOMPL" in program SAPMSSY1.
Debugging SMARTFORMS transaction code, i found the RFC function SSF_NEXT_FMNUMBER, this FM return the number which is use to generate the name of smartform function. When is called from include LSTXBF01 with destination "NONE", the RFC connection fail and can`t return the next number.
I try test RFC connection from Trx. SM59 but always return me this message "RFC error when sending logon data"
Anyone knows how resolve this problem?
Thanks and sorry for grammatical errors.
PD: I copy FM SSF_NEXT_FMNUMBER code in a custom program and with this way i can get the number i need, to modify the variable during debugging for generate the FM of Smartforms, but i'll prefer fix the RFC connection.

Hello everybody,
                         my problem is solved.For the UDConnect, whatever DATA SOURCES you create gets registered in a FUNCTION MODULE which has a capacity of only 99 enties, so to increase it implement the SAP NOTE 876340 - UDC Error available on SERVICE MARKET PLACE.
This problem occurs with BW version 3.5 level 17 or below.
Regards,
Priyanka
