Diagnosis
You tried to assign a measure (or an appropriation request) to aprogram position of investment program &V1&/&V2& that has program typeV4.
However, there is a planning lock for planning measures (orappropriation requests) for version &V3& of an investment program ofapproval year &V2& and program type &V4&. This means that the total ofthe plan values from the assigned measures and appropriation requestsfor version &V3& on this investment program is not allowed to change.But if you assign the measure (or appropriation request), the planvalue would change, since the measure (or request) has plan values forversion &V3&.

System Response
The assignment is not allowed.

Procedure
Reduce the plan value of the measure (or appropriation request) inversion &V3& to zero.
If this error occurred during processing of an appropriation request,when the request was replaced by a measure, then check all measuresassigned to the appropriation request in version &V3&, and reduce theirplan values to zero.
