Here we will discuss the following error message:
” Error entry no. 83 Error when creating Absence Quota”
” A Complex application error”

The ‘error no. 83’ can only occur in the following scenarios:
1. If a quota type that was to be generated was deleted.
2. If an employee has an organizational reassignment to a personnelsubarea or employee subgroup which have different groupings for quotatypes and for these groupings the ‘old’ quota type does not exist.

Function QUOTA checks to determine if the quota types to be generated are valid. If the quota type is not valid anymore (see reason 2) thenyou will get a warning message.

To avoid that message you should customize table T556A as my colleaguealready explained you (“… by defining a dummy quota type for the ‘old’groupings of the employee…”). Please notice that table T556A is acustomizing table.

check the customising tables T556A T559D
or check via rptquota_check if the employee has correct quota in the system

———
You need to delimit the old quota
for example
For this personnel number I can see an organizational change which means that RPTIME00 is trying to generate a quota for a validityinterval during which the employee belongs to two different groupings,due to the transfer.By groupings here I mean the “Employee Subgroup Grouping for Time QuotaTypes” and the “Personnel Subarea Grouping for Time Quota Types
