File upload from AO - Function Type customization

[Former Member]

Hi,

I am working on SAP BPC 11.0 SP 5 Embedded version. I have created planning sequences for flat file upload
using Standard Function Type - 0RSPL_FILE_UPLOAD_AO(File Upload from AO)

I've below queries related to above function type:

1) Is there any possibility to fix a value for some fields of info provider so that user need not to provide data for those fields in .csv file?
2) Is it possible to create copy of above function type and related class to customize a file upload? I tried but with that custom function type system is not giving file selection pop up for upload.

Thank you.
