In the standard Project System, the system does not check the user-defined fields in WBS elements and activities because their significance is customer-specific.

You can use this enhancement to add a check. The components of the enhancement are each accessed when you make entries in the appropriate user-defined field.

In each case, the values of the relevant object (e.g.WBS element or activity) are transferred to the function modules. There are no return parameters. If the value in a user-defined field (field name USR...) is not allowed, an appropriate error message (E...) should be output.

Enhancement CNEX0001 contains the following components:

• EXIT_SAPLCJSS_001: PS Customer-Exit for user-defined fields in the standard work breakdown structure
• EXIT_SAPLCJWB_001: PS Customer-Exit for user-defined fields in the work breakdown structure
• EXIT_SAPLCONW_001: PS Customer-Exit for user-defined fields in the network
• EXIT_SAPLCPDO_001: PS Customer-Exit for user-defined fields in the standard network
