getting compilation error for the below sql view in sap datasphere SELECT BUKRS, BUTXT, LAND1, WAERS, VKORG, WERKS, AGENCYGROUP, AGENCYBYSALES, MATNR, Agncy,

To troubleshoot and resolve the compilation error in your SQL view for SAP Datasphere, we'll go through common issues that typically lead to compilation errors. Based on your query, here are a few potential areas to check:

### 1. **Syntax Issues**
- Ensure that every keyword and function is spelled correctly and matches the SQL syntax used in SAP HANA.
- Ensure all parentheses match properly. Unmatched parentheses can lead to compilation errors.
- Check that you are not missing any commas between selected fields.

### 2. **Aliases and Naming Conflicts**
- Ensure that all table and column names, as well as aliases, are using the correct naming conventions and avoiding conflicts.
- Ensure that `RANK` is not conflicting with any reserved keywords in SQL. It's often a good idea to rename it to something more specific like `RANK_NUM`.

### 3. **Correct INNER JOIN Conditions**
- Double-check your `JOIN` conditions to ensure that they are valid and are referencing correct columns.
- Verify that the `ON` conditions corresponding to your joins are correct and complete.

### 4. **Subqueries**
- In your inner subquery where you check for `NOT IN`, ensure that the selected columns are compatible with what is expected in the outer query.
  
### 5. **Avoiding DISTINCT in SELECT with RANK**
- Utilizing `RANK()` with `DISTINCT` selection in the same query can sometimes lead to unexpected behavior. Ensure that your RANK logic makes sense and is appropriately ordered.

### 6. **Filtering Condition**
- In the outer query, your filtering condition `WHERE RANK=1 AND EA_PRICE+CS_PRICE>0` should exist only after the `RANK` is computed. Make sure that your logic lets it happen correctly.

### Example Revised Query
Here is a refined version based on the suggestions above (with some extra checks):

### Final Steps
After making these changes, try recompiling the view again. If the error persists, provide specific details about the compilation error message to further pinpoint the issue.
