Since the Item master data of Beas only displays cost centers (see the following image),
you cannot assign a distribution rule, even the one you have created:
However, you can assign a distribution rule in 3 different ways:
1. ON ACCOUNT LEVEL
After you have defined the distribution rule, apply it on account level.
Please bear in mind to change the type of account and add the distribution rule .
Please make sure you apply the distribution rule to the correct WIP account according to your setting in the Configuration wizard:
After setting this up, you can see how the distribution rule is applied for the Work order, checking it on the Cost accounting summary report:
2. IN THE BUSINESS PERFORMANCE MODULE
Here you can even define different distribution rules according to the month of the year.
3. DEFINE IT WITH SCRIPT
