How To Fix LSO602 - Prerequisite '&1' of element '&2' is missing from the curriculum type

SAP Error Message - Details

• Message type: E = Error

• Message class: LSO - Publisher and Learner Account

• Message number: 602

• Message text: Prerequisite '&1' of element '&2' is missing from the curriculum type

What causes this issue?

<ZH>&v1&</> is specified in the master data as a prerequisite for the
course type <ZH>&v2&</>.
This prerequisite is not imparted by a preceding curriculum element
(for elements <ZK>with</> suquence rules) nor is it specified as a
prerequisite for participation in the curriculum.

System Response

When a curriculum is booked, no check is carried out for the
prerequisites of the individual curriculum elements, only for the
prerequisites for the curriculum as a whole. This may result in a
situation where learners are booked for <ZH>&v2&</> whose prerequisites
they do not fulfill.

How to fix this error?

First, check that the curriculum elements are in the right sequence. A
course can only impart the prerequisites for another course if it
occurs in the sequence of elements <ZH>before</> that course. Courses
'without sequence rules ' cannot impart qualifications for other
courses in the curriculum (since they are placed at the end of the
curriculum).
You can correct the error by defining <ZH>&v1&</> as a prerequisite for
the curriculum type. You can do this in the master data catalog, for
instance.
Alternatively, if the prerequisite '&v1&' is not mandatory for the
course type '&v2&', you can delete it as a prerequisite altogether.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
