BCS - BW Change Hierarchy Validity

Hi Gurus,

I started working with BCS for the first time, and now im facing some doubts.

I have created one Hierarchy under UCWB > Process View > Master Data > Consolidation Units >.

When i created the Hierarchy, the parameters were fine (Consolidation Area and Period / Year = 01.2016).

In BW the Hierarchy was automatic created with validity from 01.2016 to 12.9999. So far so good.

Now one requirement have changed and the hierarchy needs to have validity from 12.2015. Is there an easy way to this, without delete hierarchy, change parameters and create again the hierarchy?

Thanks in advance for your help.

Regards,

JG
