• What is the cause and solution for SAP error message /STTPEC/INT_TRN_MSG029 - Obligatory parameters (MATNR or UOM) cannot be initial ?

  The SAP error message /STTPEC/INT_TRN_MSG029 indicates that certain obligatory parameters, specifically MATNR (Material Number) or UOM (Unit of Measure), cannot be left empty or initial when processing a transaction. This error typically arises in scenarios where a material or its corresponding unit of measure is required for the operation being performed, such as during data transfer, material movements, or inventory management.
  Cause:
  
  Missing Material Number (MATNR): The system expects a valid material number to be provided, but it is either missing or not correctly populated in the transaction.
  Missing Unit of Measure (UOM): Similar to the material number, the unit of measure is required for the transaction, and it is either not provided or incorrectly set.
  Data Transfer Issues: If this error occurs during data transfer (e.g., from an external system), it may indicate that the data being sent does not include the necessary fields.
  Configuration Issues: There may be configuration settings in the SAP system that require these fields to be mandatory, and they are not being fulfilled in the current transaction.
  
  Solution:
  
  Check Input Data: Ensure that the material number (MATNR) and unit of measure (UOM) are correctly populated in the transaction. If you are using a custom program or interface, verify that these fields are being filled correctly.
  Validate Material Master: Check if the material number exists in the material master and is active. You can do this by using transaction code MM03 to display the material details.
  Review Transaction Logic: If this error occurs in a custom program or report, review the logic to ensure that it correctly handles the input parameters and does not allow them to be empty.
  Data Transfer Mapping: If the error arises during data transfer from an external system, review the mapping and ensure that the required fields are being sent correctly.
  Consult Documentation: If you are unsure about the required fields for a specific transaction, refer to the SAP documentation or help files related to that transaction.
  Debugging: If you have access to debugging tools, you can trace the execution of the program to identify where the parameters are being set and why they might be empty.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material) to manage material data.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Exits and BAdIs: If you are working with custom developments, consider checking for user exits or BAdIs that might be influencing the behavior of the transaction.
  
  By addressing the above points, you should be able to resolve the error and ensure that the necessary parameters are provided for the transaction to proceed successfully.
