Diagnosis
You want to enter a meter reading on activity day &V1&. This would meanthat &V2& meter readings are entered on the same day, with at least oneof them of a technical nature (meter reading reason &V4&).

Note for error analysis:
Meter reading document number &V3& already exists for this case.

Procedure
Simplify this scenario of meter readings by deleting the ones you do notneed.
Only five meter readings can exist for this day.
Meter readings that trigger billing or that are technicalare important. For example, periodic meter readings orchanges to the installation structure. Move-in is alsoimportant.
