• What is the cause and solution for SAP error message UMG171 - Skip-flag should not be set for table category '2'. ?

  The SAP error message UMG171, which states "Skip-flag should not be set for table category '2'," typically occurs in the context of data migration or data upload processes, particularly when using tools like LSMW (Legacy System Migration Workbench) or other data transfer methods.
  Cause:
  The error is triggered when the system detects that the "Skip" flag is set for a table that is categorized as "2" (which usually indicates that the table is a mandatory table for the data upload). The "Skip" flag is used to indicate that certain records should be ignored during processing, but for tables categorized as "2," this is not allowed because the data in these tables is essential for the integrity of the transaction or process being executed.
  Solution:
  To resolve this error, you should:
  
  
  Check the Configuration: Review the configuration of your data migration project or the specific data upload process. Ensure that the "Skip" flag is not set for any mandatory tables (category '2').
  
  
  Modify the Data Mapping: If you are using LSMW or a similar tool, go to the mapping of the fields and ensure that the "Skip" flag is not activated for any of the mandatory fields or tables.
  
  
  Review the Data: Ensure that the data you are trying to upload is complete and meets all the requirements for the mandatory fields. If there are missing values or incorrect formats, correct them before attempting the upload again.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources related to the specific data migration tool you are using. There may be additional guidelines or best practices for handling mandatory tables.
  
  
  Testing: After making the necessary adjustments, perform a test run of the data upload to ensure that the error does not occur again.
