can any body tell me how can i attach budget profile to maintenance order??
and functionality wise what will be impact on the order??
If I understand your question correctly. You can assign the budget profile in the following config path
Plant maintenance & customer service ->>Maintenance and Service order ->>Functions and settings of order types ->> Configure order types.
Select your require order type and define your budget profile.
This can be used for budgeting in order level . Where you can control cost at order level.
