What causes this issue?

Contract change can either be:
?Contract modification
?Change of estimates.

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

Depending on the Customizing ( 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
In case of a prospective change the system performs a prospective split
on the deferral items. The deferral item which corresponds to an open
reconciliation key in the period of the contract change is flaged with
the prospective split flag (PRO_SPLIT = 'X').
The split amount represents the revenue amount posted plus the scheduled
revenue amount from the period prior to the current change.
The example below illustrates this:
RECON_KEY,,POB_ID,,CONDITION_TYPE,,REV_AMT_DELTA,,REV_AMT_POSTED,,
PRO_AMT_CUMULATE,,HAS_PRO_SPLIT,,LATEST_DEFITEM
201802001,,POB1,,PR00,,1000.00,,0.00,,0.00,,-,,-
201803001,,POB1,,PR00,,1000.00,,1000.00,,0.00,,-,,-
201803002,,POB1,,PR00,,- 500.00,,1000.00,,1000.00,,X,,-
201804001,,POB1,,PR00,,1000.00,, 500.00,,1000.00,,-,,-
201805001,,POB1,,PR00,,1000.00,,1500.00,,1000.00,,-,,X
In this example, a contract modification was performed in period
2018/03. Therefore the split amount is calculated and the prospective
split flag set. All deferral items, beginning from the contract change
period, are updated with the split amount (PRO_AMT_CUMULATE).
If the split amount is not the total of the posted and scheduled revenue
from the previous period (not necessarily previous reconciliation key!),
a C26 inflight check error is raised.
