• What is the cause and solution for SAP error message RSDRV_VPROHANA021 - Attr. &1 (Nav. Attr. &2) contains small letters (not allowed in SAP BW) ?

  The SAP error message RSDRV_VPROHANA021 indicates that there is an issue with the naming convention of attributes in SAP BW (Business Warehouse). Specifically, the error states that the attribute (or navigation attribute) contains lowercase letters, which are not allowed in SAP BW.
  Cause:
  In SAP BW, naming conventions are strict, and attributes must adhere to specific rules. One of these rules is that attribute names should only contain uppercase letters, numbers, and underscores. The presence of lowercase letters in the attribute name violates this rule, leading to the error message.
  Solution:
  To resolve this error, you need to rename the attribute or navigation attribute to ensure that it only contains uppercase letters, numbers, and underscores. Here are the steps to do this:
  
  
  Identify the Attribute: Determine which attribute is causing the error. The error message will provide the names of the attributes involved (e.g., Attr. &1 and Nav. Attr. &2).
  
  
  Access the Data Model: Go to the relevant InfoObject or data model in the SAP BW system where the attribute is defined.
  
  
  Rename the Attribute:
  
  Open the InfoObject in the SAP BW modeling tools.
  Locate the attribute that contains lowercase letters.
  Change the name of the attribute to use only uppercase letters, numbers, and underscores. For example, if the attribute is named customerName, you could rename it to CUSTOMER_NAME.
  
  
  
  Activate the Changes: After renaming the attribute, make sure to activate the InfoObject or data model to apply the changes.
  
  
  Test the Changes: After activation, test the data model or query to ensure that the error no longer occurs.
  
  
  Related Information:
