  1. Cause:
  
  The error WXP779 typically occurs during the execution of Web Dynpro applications or when working with Web Dynpro components that involve internal tables or context nodes.
  Specifically, the message indicates a problem when inserting data into the internal table TWISPC_PLSCH_W.
  The ampersand (&) in the message is a placeholder for additional information or the specific error detail.
  Common causes include:
  
  Attempting to insert a duplicate key into a table that requires unique keys.
  The internal table TWISPC_PLSCH_W is defined as a sorted or hashed table, and the insertion violates the uniqueness constraint.
  Data inconsistency or incorrect data being passed to the table.
  Programming error where the insert statement is not properly guarded against duplicates.
  
  
  
  
  2. Solution:
  
  
  Check the Data Being Inserted:
  
  Verify the data that is being inserted into the table TWISPC_PLSCH_W.
  Ensure that the key fields of the table are unique for each insert operation.
  
  
  
  Modify the Insert Logic:

  For example, before inserting, check if the entry already exists using READ TABLE or use INSERT ... INTO TABLE ... TRANSPORTING NO FIELDS with proper handling.
  
  
  
  Change Table Type (if applicable):
  
  If the table is defined as a hashed or sorted table and duplicates are expected, consider changing the table type to a standard table (if business logic allows).

  Debug the Web Dynpro component or ABAP program where the insertion happens.
