MESZ:Error is :: <nobr>[Line: 2,211 Field: 1] (-971) -ERROR: Invalid POSITIVE NUMBER value</NOBR><br><nobr>The data found at the row 2,211 has invalid data for the given configuration</NOBR><BR>
Cause:
When the project module was introduced in 3800 (later reverted in 3900) the column's datatype was created in the template as 'Positive number'.
But in the latest build (in A+ 3950) datatype of 'TimeSpent in Minutes' in the tables 'Status History','Technician History' and 'Support Group History' created as 'Number' datatype.
This issue is more likely to happen with Latest SDP (9422 and above).
Fix:
Follow the below steps to change the datatype to Number in the problematic tables.
Run the query "update zdbdbobjectprops set propvalue='false' where objid=<OBJID> and propkey='zdb.system.table'" by connecting database
