Saving comments as short-text on SAP BPC 10.1 Embedded

Hi everyone,

I am trying to enable the comments functionality in my planning model for BPC 10.1 Embedded.

I have gone through some forums earlier and have carried out the following steps to save the comments as a short-text:

1. Created a DSO (Direct-Update) and set the Planning Mode to ON.

2. Added a characteristic in the Data Fields and set the Characteristics as Key Figure as ON within the DSO.

3. Created a MultiProvider on my Planning Cube  and the DSO.

4. Created an Aggregation level on the MultiProvider.

5. Created an Input-Enabled query and added "Amount" and "Comment" in the Key Figures.

6. Created an EPM Input Form. Version of EPM (10.0 SP 25 Patch 1 .NET4)

7. While saving the data, getting an error as below:

Kindly Help!
