Many of the actions that can change an internal order are defined in the system as business transactions. These business transactions are represented by a four-character key and a descriptive text. Examples are:

RKP1 Planning costs

KZPP Planned overhead (periodic)

KZPI Actual overhead (periodic)

BFRE Release

RFBU G/L account postings

RKU1 Reposting costs

RKL Activity Allocation

KOAO Actual settlement

LVMS Set deletion flag

If you change an internal order, the system checks whether the corresponding business transaction is allowed for that internal order in the current status.
