• What is the cause and solution for SAP error message CNV_DMC_WDA101 - Select only one row ?

  The SAP error message CNV_DMC_WDA101: Select only one row typically occurs in the context of data migration or conversion processes, particularly when using the SAP Data Migration Cockpit (DMC) or similar tools. This error indicates that the system expects the user to select a single row from a list or table, but multiple rows have been selected instead.
  Cause:
  
  Multiple Selections: The most common cause of this error is that the user has selected more than one row in a table or list where only a single selection is allowed.
  User Interface Issue: Sometimes, the user interface may not clearly indicate that only one selection is permitted, leading to confusion.
  Data Integrity: The process may require a unique identifier or a specific record to be processed, and selecting multiple rows violates this requirement.
  
  Solution:
  
  Select a Single Row: Review the list or table from which you are making a selection and ensure that you only select one row. Deselect any additional rows that may have been inadvertently selected.
  Check for Filters: If applicable, apply filters to narrow down the selection to the desired row before making a selection.
  Review Documentation: Consult the relevant SAP documentation or user guides for the specific transaction or process you are working with to ensure compliance with selection requirements.
