Hello BS,
I am not sure if you have referred 737230 - Consulting: Planning in technical periods. This issue is clarified in this SAP Note. Please check.
( http://service.sap.com/sap/support/notes/737230 )
"Use Storage Bucket Profile' option in Planning Book lets you display the data in technical periods. Due to limitation with specifying 9ASTORAGE as time bucket profile in Planning Book Design, it is not possible to display data in the planning book in technical period constantly(or by default).
By creating Fiscal Year Variant you can map time buckets to exact technical periods and assigning this Fiscal Variant to Storage Bucket Profile.
Text from above SAP Note -
For example, if you want to execute mass processing jobs for these technical periods (for example, to influence time-based disaggregation), you can create a fiscal year variant that maps the technical periods. This means that you must create periods that always have the corresponding end of the week or month as the end date. This fiscal year variant must then be assigned to the storage buckets profile of the planning area, so that planning buckets profiles with this periodicity are assigned to the data view. The periods in the data view can then be used, and macros for these periodicities can then be created accordingly.

Hope this will help.
Thank you
