• What is the cause and solution for SAP error message MMRP01007 - Row already existed when inserting into the matrix ?

  The SAP error message MMRP01007, which states "Row already existed when inserting into the matrix," typically occurs in the context of SAP Business One when there is an attempt to insert a new row into a matrix (like a grid or table) that already contains a row with the same key or identifier. This can happen in various scenarios, such as when adding items to a document or when working with user-defined fields.
  Causes:
  
  Duplicate Entry: The most common cause is that the row you are trying to insert already exists in the matrix. This could be due to a previous entry that was not properly cleared or removed.
  Key Violation: The matrix may have a unique constraint on certain fields, and the new entry violates this constraint.
  Data Integrity Issues: There may be issues with the data being processed, such as incorrect or incomplete data that leads to a conflict.
  User-Defined Fields: If you are using user-defined fields, there may be conflicts with existing data.
  
  Solutions:
  
  Check for Duplicates: Before inserting a new row, check if the row already exists in the matrix. You can do this by querying the existing data or checking the matrix for the specific key or identifier.
  Clear Existing Rows: If you are trying to insert a new row but the existing row is not needed, consider removing or clearing the existing row first.
  Review Unique Constraints: If the matrix has unique constraints, ensure that the data you are trying to insert does not violate these constraints.
  Debugging: If you are developing or customizing the application, use debugging tools to trace the code and identify where the duplicate entry is being attempted.
  Consult Documentation: Review the SAP Business One SDK documentation or relevant SAP notes for any specific guidance related to the error message.
