Hi Alecsandra,
Although I haven't physically done this myself, my understanding is as follows:
- define dataload key figure at aggregate level (eg brand-customer group for master data types product-customer) with base planning level brand-customer group (the planning level can have roots at any attribute level not necessarily at the master data type key field level)
-create a second key figure with base planning level at the key-field level of the master data types eg product-customer. Associated with this key figure, define a basis for disaggregation from brand-customer group down to product-customer.
- via key figure calcs for the second key figure, assign the first key figure and you should then be able to load at aggregate level but use the data at lower levels.
If you disagree pse let me know!
Rgds
