Time constraints in SAP

Time Constraint 1

  • For the entire time that the employee works at the enterprise, exactly one valid info-type record must exist at any one time.
  • The validity periods of the individual records must not overlap.
  • If a new record is created, the system automatically uses the start date of the new record as the delimitation date of the old record.
  • Gaps are only allowed between the employee’s entry date and the start date of the first record.

Time constraint 1 must be used for all of the info-types containing information that must be available at all times. This is particularly true of personal and organizational assignment data.

If a record is delimited because of time constraint 1, the system displays an appropriate message.

Time Constraint 2

  • No more than one valid record can exist at any one time.
  • Records with constraint 2 must not overlap.
  • Their existence is not compulsory.
  • Note that the first 2 conditions are pretty much similar to Time Constraint 1, except the third condition.
  • If a new record is created, the system automatically delimits the previous record, if one exists.

If a record is delimited because of time constraint 2, the system displays an appropriate message.

Time Constraint 3

  • Any number of valid records can exist at any one time.
  • The individual records do not conflict with each other.

The system also contains the following time constraint indicators:

Time Constraint A
Info-types with time constraint A must have no more than one record. The system automatically assigns the record a
validity period from January 01, 1800 through December 31,9999. This validity period cannot be subdivided.

Info-type records with time constraint A cannot be deleted.

Time Constraint B
Info-types with time constraint B must have no more than one record. The system automatically assigns the record a
validity period from January 01, 1800 through December 31,9999. This validity period cannot be subdivided.

Info-type records with time constraint B can be deleted.

Time Constraint T
Info-type records with time constraint T depend on the subtype.

The principles of data entry and time constraints that apply to info-types ensure that data is consistent and accurate. They also constitute the basis of time recording, payroll accounting, and reporting.

Time Constraint Z: Time management Info-type T554Y

For some time management info-types, the record is for the time period (which may be a part of the day)
