  The SAP error message TDL_INV_BAPI018: Unit of measure was not specified typically occurs when you are trying to create or update an inventory document or transaction using a BAPI (Business Application Programming Interface) and the unit of measure (UoM) for a material is not provided or is missing.
  Cause:
  
  Missing Unit of Measure: The most common cause is that the unit of measure for the material being processed is not specified in the data being sent to the BAPI.
  Incorrect Data Mapping: If you are using a custom program or interface, the mapping of fields may not be correctly set up, leading to the omission of the UoM.
  Material Master Data Issues: The material master data may not have a defined unit of measure for the specific material or plant combination.
  Configuration Issues: There may be configuration issues in the system that prevent the UoM from being recognized.
  
  Solution:
  
  Check Input Data: Ensure that the input data being sent to the BAPI includes the unit of measure for the material. This is typically done in the structure that holds the item details.
  Review Material Master: Verify that the material master record has a valid unit of measure defined. You can check this in transaction MM03 (Display Material) under the Basic Data or Purchasing views.
  Update Mapping: If you are using a custom program or interface, review the mapping of fields to ensure that the unit of measure is being correctly populated.
  Use Default UoM: If applicable, you can set a default unit of measure in the material master or in the configuration settings for the BAPI.
  Check BAPI Documentation: Review the documentation for the specific BAPI you are using to ensure that you are providing all required fields, including the unit of measure.
  
  Related Information:
