BPC 10.1 - Modify data in PGROUP member

Hi all,

I am working in BPC 10.1 standard and I need to modify the data of my "PGROUP" member in my "O_ACCT" dimension of my Ownership model. I have tried to set up the property "IS_INPUT" to "Y" for "PGROUP" member but it still isn´t appear in my Ownership manager. Does anyone know how can I modify the data for that member?

Thanks in advance!

Regards,

Cristina.
