    <ZH>RKL</> (Direct Activity Allocation):
    Category 1 (manual entry, manual allocation)
    <ZH>RKN</>, <ZH>RKIL</> (Indirect Activity Allocation):
    Category 3 (manual entry, indirect allocation)

    Category 2 (indirect calculation, indirect allocation)
    <ZH>RKPS</> (Template Allocation Plan):
    Category 1 (manual entry, manual allocation)
    Category 2 (indirect calculation, indirect allocation)

    You can post category 2 (indirect calculation, indirect allocation) and

    allocation) activity types

    set in the activity type master data.
    If this indicator is set for an activity type of category 1, 2 or 5,
    you can post the activity types in the same posting transaction (entry
    of sender activities) and together with activity type categories
    3 and 4.

    How to fix this error?

    Enter an activity type with a category valid for business transaction
    &V2&.
    <ZH>Note</>
    If you have not yet carried out <ZH>any</> postings in actual or plan,
    you can overwrite the activity type category defined in the activity
    type master record <ZH>in planning</>.
    This activity type category is then valid for the entire fiscal year in
    both actual and plan. Making a change to master data at a later date
    affects the <ZH>current</> fiscal year and therefore <ZH>not</> the
    current posting.
