Characteristic based forecast consumption for STO in APO

[Former Member]

Hi

We have a requirement where we forecast at the customer level and consume at the customer level, For Sales orders we achieve that by populating field catalogue using user exit FV45VFZY_USEREXIT_CATALOG_VALU and using consumption group in Product master, I would like to know how we can achieve this for STO, is there a similar field catalog user exit that can be used to populate the structure and which can be mapped to the consumption group field elements.

Appreciate your inputs.

Thanks
