Create a check of user-defined fields in a standard WBS

The following SAP enhancement is available for checking user-defined fields in the Project System:

CNEX0001 Checking user fields

In the standard Project System, user-defined fields in WBS elements and network activities are not checked because each customer can define them differently.

You can use this enhancement to check user-defined fields. When the user makes an entry in a user-defined field, the system automatically calls the appropriate enhancement component.

The values of the individual objects (for example, WBS element or activity) are transferred to the function modules. However, there are no parameters which allow you to transfer values back.

Create an error message with message type E, that is issued when the user enters an invalid value in a user-defined field (Field name USR...).

Enhancement CNEX0001 contains the following enhancement components:

EXIT_SAPLCJSS_001: for standard work breakdown structures

EXIT_SAPLCPDO_001: for standard networks

EXIT_SAPLCJWB_001: for work breakdown structures

EXIT_SAPLCONW_001: for networks

Activities

1. Create the enhancement.

To do this, either create a new project or use an existing one.

2. Activate the project.

Only once you have activated the project, will your enhancement take effect.

Further Notes

Enhancements - as opposed to modifications - are not influenced by a release upgrade because they are not part of the original SAP programs, rather, they exist in an area reserved for customers.

You will find a general procedure for creating enhancements in the enhancement transaction under Tools -> Online Handbuch.

Each enhancement has its own documentation. You can access this documentation by clicking on Display SAP Doc. in the enhancement transaction.
