I found an old post regarding "Milestone Billing" in this community and tried to follow the steps.
I could "Create New Item Category", however, I cannot complete "Assign Item Category".
I assume it cannot be assigned because
Item Category I created(ZTAS, ZTAD, ZTAS) are not found in the selection list.
How can I assign Item Category I created(ZTAS, ZTAD, ZTAS) to Sales Document Type?
These are steps I've tried..
.Create New Item Category, say ZTAN - Copy of TAN (For delivery Related) / ZTAD - Copy of TAD (For Order realted) / ZTAS - copy of TAS (For Third Party)
Maintain as under (others remaining same)
Billing Relevance: I
Billing Plan Type: 01
IMG > Sales and Distribution > Sales > Sales Documents > Sales Document Item > Define Item Category
.Assign Item Category, for ex (assuming Usage & higher level item category as blank):
Sales Document Type | Item Category Group | Default Item Category
ZOR | NORM | ZTAN
ZOR | DEIN | ZTAD
ZOR | BANS | ZTAS
IMG > Sales and Distribution > Sales > Sales Documents > Sales Document Item > Assign Item Category
thank you for your support in advance!
