How do I implement MDG Mass Approval for multiple workflow items in the inbox?

Implement a custom MDG POWL based on CL_USMD_CREQUEST_POWL, enable multi-selection, map the inbox application/query/type, maintain the inbox customizing tables, and add feeder logic so only selected tasks with identical MDG actions are processed together.

SOLUTION SUMMARY · SHORT ANSWER

MDG Mass Approval is implemented by creating a dedicated POWL inbox that allows checkbox-based multi-selection and then wiring the inbox to MDG workflow tasks and actions. The source guide uses a custom feeder class derived from CL_USMD_CREQUEST_POWL, a POWL application ID, POWL type, query, and inbox customizing so users can select several change requests and trigger one common action for all compatible items.

Process flow

Create a custom feeder class inheriting from CL_USMD_CREQUEST_POWL
Create a POWL Application ID using FPB_MAINTAIN_HIER
Create a POWL Type using POWL_TYPE
Map Application ID to POWL Type using POWL_TYPER
Create the POWL Query using POWL_QUERY
Map Application ID to Query using POWL_QUERYR
Create a component configuration for POWL_UI_COMP
Configure multi-selection in the POWL UI context node confData if needed by the UI stack in use','Create a component configuration for IBO_WDC_INBOX','Assign the custom POWL Application ID to node powl','Create an application configuration,

FPB_MAINTAIN_HIER

Personalization Hierarchy / Personalization Application

Create the Mass Approval POWL application ID Z_CREQUEST_MASS_APRVL_POWL

POWL_TYPE

Create POWL type and assign feeder class

Define Z_CREQUEST_POWL_TYPE and link it to ZCL_CREQUEST_MASS_APRVL_POWL

POWL_TYPER

Map Application ID to POWL Type

Assign Z_CREQUEST_MASS_APRVL_POWL to Z_CREQUEST_POWL_TYPE

POWL_QUERY

Create query and set refresh/query parameters

Define Z_CREQUEST_POWL_QUERY, refresh type, and work item selection

POWL_QUERYR

Map Application ID to Query

Assign Z_CREQUEST_MASS_APRVL_POWL to Z_CREQUEST_POWL_QUERY with category USMD_CREQUEST_DEFAULT
