• What is the cause and solution for SAP error message SALV_X_API122 - Quantity colum &1 requires an unit ?

  The SAP error message SALV_X_API122 indicates that there is an issue with a quantity column in an ALV (ABAP List Viewer) report. Specifically, the error states that the quantity column requires a unit of measure (UoM) to be defined. This typically occurs when you are trying to display or manipulate data that includes quantities, but the system cannot determine the unit of measure for those quantities.
  Cause:
  
  Missing Unit of Measure: The most common cause of this error is that the quantity field in your data does not have an associated unit of measure. This can happen if the data source does not provide a UoM or if the UoM is not correctly mapped in the ALV configuration.
  Incorrect Data Mapping: If the data being passed to the ALV does not include the necessary fields for unit of measure, or if the fields are incorrectly defined in the data structure.
  Configuration Issues: There may be issues in the ALV configuration or the way the data is being prepared for display.
  
  Solution:
  
  Check Data Source: Ensure that the data source you are using to populate the ALV contains a valid unit of measure for the quantity fields. If the UoM is missing, you will need to update the data source to include it.
  Modify Data Structure: If you are using a custom data structure, make sure that the unit of measure field is included and correctly defined in the structure.
  ALV Configuration: Review the ALV configuration to ensure that the quantity column is correctly set up to reference the unit of measure. This may involve checking the field catalog or the layout settings in your ALV report.
  Debugging: If you are still encountering issues, consider debugging the ALV report to trace where the data is being populated and to verify that the unit of measure is being passed correctly.
  
  Related Information:
  
  Unit of Measure Tables: Familiarize yourself with the relevant SAP tables that store unit of measure information, such as T006 (Units of Measure) and T006A (Units of Measure: Language-Dependent Texts).
  ALV Documentation: Review SAP documentation on ALV reporting to understand how to properly configure and manage data fields, including units of measure.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on handling unit of measure in ALV reports.
  
  By ensuring that the unit of measure is correctly defined and associated with the quantity fields in your ALV report, you should be able to resolve the SALV_X_API122 error.
