Functionality

You can use this module to change constraints in liveCache.

Parameters:

• IT_CONSTRAINTS: The constraints listed in this table are created, changed, or deleted in liveCache.

• IV_METHOD: Method with which the constraints will be changed. Valid methods are:

• gc_new: The specified constraints are created in liveCache.

• gc_change: The constraints are changed in liveCache as specified in IT_CONSTRAINTS.

• gc_change_or_new: If the constraints already exist in liveCache, they are changed as specified; otherwise they will be created.

• gc_delete: The specified constraints are deleted.

This module replaces the module OM_CHANGE_EXT_CONSTR, which could only be used to create constraintsoutside of top orders. It is now no longer possible to create multiple external constraints with the same constraint key. The key consists of the following fields:

• ACTID_PRED

• ACTID_SUCC

• CONSTRAINT_TYPE

• CONSTRAINT_SUB_TYPE

• RELATION_TYPE

• MODE_REL_TYPE

• TERMINATED_BY_SUCC

• TERMINATED_BY_PRED

Example

Notes

The following lists the most important liveCache error messages. If an LC_COM_ERROR or LC_APPL_ERRORerror (exceptions) occurs while this module is being processed, all changes made in the liveCache are always completely reversed.

• 28 = Reflexive constraint: Predecessor and successor activity are identical.

• 34 = om_invalid_method: Invalid method; only the methods listed above are valid

• 43 = om_invalid_segment: At least one of the two activities to be linked by a constraint does not exist in liveCache.

• 18615 = om_duplicate_constraint: A constraint with the specified key fields (see above) already exists in liveCache.
