How To Fix RSDD720 - &2 table: block characteristic &3, number of blocks: &4

SAP Error Message - Details

• Message type: E = Error

• Message class: RSDD - Message class for data manager

• Message number: 720

• Message text: &2 table: block characteristic &3, number of blocks: &4

What causes this issue?

The number of records in the &V2&- table of the source is larger than
the parameter BLOCKSIZE in table RSADMINC. For this reason, aggregates
must be constructed block by block. To do so, a characteristic with
sufficient values is selected from the aggregate or the source. These
values are then distributed into blocks. Read and write access then
always takes place on an individual block level.
Block characteristic: &V3&.
Number of blocks: &V4&
Note: If the selected block characteristic has a very uneven data
distribution, it may be that the blocks are larger than specified by the
BLOCKSIZE parameter.

• What is the cause and solution for SAP error message RSDD720 - &2 table: block characteristic &3, number of blocks: &4 ?

  The SAP error message RSDD720 typically relates to issues with the data model in SAP BW (Business Warehouse) or SAP BW/4HANA, specifically concerning the characteristics and their blocks in the InfoProvider. This error indicates that there is a problem with the data loading process, particularly with the characteristics that are being blocked.
  Cause:
  
  
  Blocked Characteristics: The error message indicates that certain characteristics are blocked, which means that they cannot be processed or loaded due to various reasons such as:
  
  The characteristics are not properly defined in the InfoObject.
  There are inconsistencies in the data model or the data itself.
  The data load process is encountering issues with the data source or transformation rules.
  
  
  
  Data Model Issues: There may be issues with the data model, such as incorrect settings or configurations in the InfoProvider or InfoObject.
  
  
  Data Integrity Issues: There may be data integrity issues, such as missing or incorrect data in the source system that is causing the load to fail.
  
  
  Solution:
  
  
  Check Characteristics Configuration: 
  
  Go to the InfoObject maintenance and check the configuration of the blocked characteristics. Ensure that they are correctly defined and activated.
  
  
  
  Review Data Load Process:
  
  Check the data load process and transformation rules. Ensure that the source data is correctly mapped to the target InfoProvider.
  
  
  
  Analyze Data:
  
  Use transaction codes like RSA1 (Data Warehousing Workbench) to analyze the data load process. Look for any errors or warnings in the data load monitor.
  
  
  
  Check for Data Integrity:
  
  Verify the source data for any inconsistencies or missing values that could be causing the load to fail. Ensure that the data adheres to the expected format and constraints.
  
  
  
  Reprocess the Data Load:
  
  After addressing the issues, reprocess the data load. You may need to delete the previous load and start fresh.
  
  
  
  Consult SAP Notes:
