- Variable &1 is derived and cannot be changed ?The SAP error message SIW512 indicates that a variable (denoted as &1) is derived and cannot be changed. This typically occurs in the context of SAP Business Warehouse (BW) or SAP Analytics Cloud (SAC) when working with queries, variables, or data models.
Cause:
- Derived Variable: The variable in question is derived from another variable or a calculation. Derived variables are typically calculated based on other data and are not meant to be manually changed by users.
- Query Design: The variable may be part of a query definition where its value is automatically calculated based on the underlying data model or logic.
- Data Source Restrictions: The data source or the context in which the variable is being used may impose restrictions on changing derived variables.
Solution:
- Check Variable Definition: Review the definition of the variable in the query or data model. If it is indeed a derived variable, you will need to understand its source and how it is calculated.
- Use Alternative Variables: If you need to change the value for analysis or reporting, consider using a different variable that is not derived or create a new variable that meets your requirements.
- Modify Query Logic: If you have access to modify the query or data model, consider adjusting the logic to allow for user-defined input or to create a new variable that can be changed.
