Create Customer-Specific Fields in a Standard Network (SAP Library

Create Customer-Specific Fields in a Standard Network

The following SAP enhancement is available for standard networks in the Project System:

CNEX0005 Customer-specific fields in standard networks

The data for standard networks is stored in database tables.

You can use this enhancement to add new customer-specific fields to standard network activities in table PLPO. To process these fields you can create your own screen, which the user can call up when maintaining standard networks.

The enhancement CNEX0005 contains the following enhancement components:

Menu entries:

SAPLCNCU+CU1

Function exits:

EXIT_SAPLCPDO_002 for transfering data to your own program
EXIT_SAPLCPDO_003 for transfering data from your program to R/3

Screen areas:

SAPLCPDO2999_CUSTSCR1_SAPLXCN10500

Activities

1. Create the enhancement.
To do this, either create a new project or use an existing one.

2. Create structure CI_PLPO in ABAP/4-Dictionary (Transaction SE11) in your own development class.

3. Expand structure CI_PLPO to include your own fields.
Please note:

to use the name ranges reserved for customers

the maximum number of fields in the database table is 255 (in PLPO and CI_PLPO, that is for both the SAP standard fields and user-defined fields). SAP reserves the right to add new fields to table PLPO; if the maximum number is reached, your user-defined field could be removed.

Activate the structure.

4. Maintain the enhancement components:

Assign the function customer fields a name.

Add to the program coding for the function exit EXIT_SAPLCPDO_002. This function exit transfers SAP data to your part of the program.
To do this, call up the function module and double-click on the include line. Create the include module.

Add to the program coding for the function exit EXIT_SAPLCPDO_003. This function exit takes the data from your part of the program and transfers it to the SAP standard program. Create your own corresponding include module.

Create the screen area.

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

Note for Batch-Input

If you want to fill your customer-specific fields later via batch-input you must take screen SAPLCPDO 2999 into consideration.

Further Notes

Unlike modifications, enhancements 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.

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

New user-defined fields do not appear automatically in the information system. To display these fields in the information system execute report program RCNCT001. The procedure is described in the documentation for the program.
