What causes this issue?

Contract change can either be:
Contract modification
Change of estimates.
Depending on the Customizing (
<DS:SIMG.FARR_VC_ACCT_PR>Configure Accounting Principle-specific
Settings</>) for a company code and accounting principle, one or the
other is applied when the scope of a contract is changed.
The change mode for a POB is determined by the field CHANGE_MODE (only
in the buffer, not written to database) and can be one of the following:
'P' or 'V' prospective change
'R' retrospective change
' ' (empty) no change
Prospective change
When a POB has change mode 'P' or 'V', then it must also have the
following flag:
HAS_PRO_CHANGE = X
unless it is newly created (CRT_FLAG = X). The POB must also have a
corresponding record inserted into the database table FARR_D_CHANGE_TYPE
with the following flag:
PRO_EFFECTED = X
again, unless it is newly created.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Retrospective change
When a POB has change mode 'R', then the field HAS_PRO_CHANGE must be
empty.
The POB must also have a corresponding record inserted into the database
table FARR_D_CHANGE_TYPE with the field PRO_EFFECTED being empty.
Negative example:
The performance obligation POB1 has a prospective change but the field
CHANGE_MODE determines a retrospective change.
POB ID,,CHANGE_MODE,,HAS_PRO_CHANGE
POB1,,R,,X
The check is not performed for POBs with CHANGE_MODE = ' '.
Buffers checked:
POB data buffer : MTS_POB_DATA_BUFFER
Change type data buffer: MTS_CHANGE_TYPE_BUFFER

System Response

The RAI processing is stopped or the manual transaction from the UI is
stopped.
