A time constraint indicates whether more than one infotype record may be available at one time. The following time constraint indicators are permissible:
1 = An infotype record must be available at all times. This record may have notime gaps. You may not delete the record last stored on the database because all records of this infotype would otherwise be deleted.
2 = Only one record may be available at one time, but time gaps are permitted.
3 = Any number of records may be valid at one time, and time gaps are permitted.
Other possible time constraint indicators are as follows:
A = Only one record may ever exist for this infotype. It is valid from 01/01/1800 to 12/31/9999. Splitting is not permissible.
View V_T582B Infotypes Which are Created Automically controls whether the system automatically creates the infotype record for an employee hiring or an applicant data entry action.
Infotypes with time constraintA may not be deleted.
B = Only one record may ever exist for this infotype. It is valid from 01/01/1800 to 12/31/9999. Splitting is not permissible.
Infotypes with time constraint B may be deleted.
T = The time constraint varies depending on the subtype.
Z: Refers to time management infotypes. The time constraint for these infotypes depends on the time constraint class defined in view V_T554S_I Absence: General Control. Collision checks are defined in view V_T554Y TimeConstraint Reaction.
1 = Record must have no gaps, no overlappings
2 = Record may include gaps, no overlappings
3 = Record may include gaps, can exist more than once
A = Infotype exists just once from Jan.1 1800 to Dec.12 9999
B = IT exists for maximum of once from Jan.1 1800 to Dec.12 9999
T = Time constraint is based on subtype or subtype table
Z = Time constraint for time management infotypes -> T554Y
Thanks for ur information and we have any option in sap system for search of particular topic.For example if i want to know about time constraints or anything directly if i want to search about the particular topic .Actually we have f1 if i search that particular time constraints only we can give f1 otherwise we dont know where it is right.Is there any option we have.
