Soap problem for Account Module

[frankhuang]

Dear ,

Please help me for this urgent problem !!!

I use sugar soap to get data from sugarCRM. when i call "get_available_modules()", i can get below modules:

Contacts
Accounts
Campaigns
Emails
Reports
....

i can get all available modules name, but when use get_module_fields($seesion_id, "Accounts") to get field from Account Module, i can't get anything, but when i use other module name, for example "Contacts", "Reports"... i can get data. and try to print the array object for get_module_fields($seesion_id, "Accounts") , i also can't see anyting in the page, no error message. dear, any idea for the problem, why only Accounts module i can't get data, but Accounts also display in the available modules listing ???

Please help me for this urgent problem, thanks thanks very much!!
