How To Fix MA287 - Not possible to calculate proportional factors

SAP Error Message - Details

• Message type: E = Error

• Message class: MA - Sales and Operations Planning

• Message number: 287

• Message text: Not possible to calculate proportional factors

What causes this issue?

There are two possible causes for this error:
You have entered an information structure for which delta planning has
been defined.
Proportional factors are not relevant for delta planning because this
planning method does not support disaggregation.
You have entered an information structure for which:
the characteristic values combination (planning hierarchy) has not been
fully maintained
or for which no version exists
or for which no data (key figure values) has yet been saved

System Response

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

How to fix this error?

RESET N1
Enter an information structure for which consistent or level-by-level
planning has been defined.
Check and, if necessary, change the planning hierarchy and check to see
that a version containing data exists for this information
structure.
