• What is the cause and solution for SAP error message DMC_RT_GEN037 - ROWID selection only possible for migrat. objects with exactly one table ?

  The SAP error message DMC_RT_GEN037 indicates that there is an issue with the selection of ROWIDs in the context of data migration or data transfer processes. This error typically arises when you are trying to perform operations that require a unique identification of rows in a database table, but the operation is being applied to a data object that does not meet the necessary criteria.
  Cause:
  The error occurs when:
  
  You are attempting to select ROWIDs for a migration object that is associated with multiple tables instead of a single table.
  The data migration or transformation process expects a one-to-one mapping between the migration object and a single database table, but the object in question is linked to multiple tables.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Migration Object Configuration:
  
  Review the configuration of the migration object you are working with. Ensure that it is defined to work with a single table. If it is meant to work with multiple tables, you may need to adjust your approach.
  
  
  
  Modify the Data Model:
  
  If your migration scenario involves multiple tables, you may need to create separate migration objects for each table or adjust your data model to ensure that the operation can be performed on a single table.
  
  
  
  Review Data Mapping:
  
  Ensure that the data mapping and transformation logic are correctly set up to handle the data from a single source table. If you are trying to combine data from multiple sources, consider preprocessing the data to consolidate it into a single table before migration.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation related to the Data Migration Cockpit (DMC) or the specific migration tools you are using. There may be guidelines or best practices for handling such scenarios.
  
  
  
  Seek Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support or consulting with a technical expert who has experience with data migration in SAP environments.
