You want to evaluate the data of a particular task within the WIS. This data:

• Is made up of the contents of the container elements of the task container
• Can be retrieved using expressions that refer to elements of the task container

Analyze the container definition of the single-step task.

Determine which container elements are relevant for the evaluation. Note that you can also access the attributes of any object references in the container elements.

Establish the associated data element for each field that is relevant for the evaluation.

Extend the ABAP Dictionary structure (communication structure) MCWF_TRANS by adding the fields that you need for you own analysis.

In a second step, the customer fields that have just been defined have to be filled with data.

The function module (user exit) EXIT_SAPLMCWF_001 has to be programmed for this.

Make the following settings in Customizing of the Logistics Information System:

• Maintain user-defined field catalogs
• Maintain user-defined information structures
• Updating definition
• Standard analyses

The extension of the communication structure MCWF_TRANS and the user exit EXIT_SAPLMCWF_001 ensure that the periodic background job RMCADATA passes the customer scenario-specific data to the LIS, as well as the SAP data.

The data then passes to the information structures S<xxx> according to the update rules, and can be used for standard analyses.
