SAP Error Message - Details

• Message type: E = Error

• Message class: 5A - Basis Personnel Management

• Message number: 441

• Message text: Maintained schedule cannot be used for planning -> F1

What causes this issue?

The schedule you have maintained is not applicable to business event
planning because it only consists of the business event duration in
days and hours. However, business event planning requires a schedule
with an exact sequence of day descriptions (either a day schedule from
table T770B, or a user-defined schedule using the "user-defined
schedule" function).
User action:
When changing a schedule by using the "Change" function, you must
ensure that the resulting schedule contains either a valid day schedule
from table T770B, or a user-defined schedule, which you can enter by
using the "user-defined schedule" function.
