Delete duplicate records from table

Sometimes we lost unique identity check in the tables while doing some customization in Dynamics AX. It may happen due to failure of database synchronization.

Here is the code to remove the duplicate records from a table, I used Dimension table as an example;

static void deleteduplicate(Args _args)
{
    set fieldSet = new set(Types::Integer);

    // create dicindex from the unique index
    DictIndex dictIndex = new Dictindex(tablenum(Dimensions),indexnum(dimensions, DimensionIdx));
    ;

    // these are the fields from the index
    // add them to a set
    fieldset.add(fieldnum(Dimensions, DimensionCode));
    fieldset.add(fieldnum(Dimensions, Num));

    // set allow duplicates
    ReleaseUpdateDB::indexAllowDup(dictIndex);


    // delete duplicate records
    ReleaseUpdateDB::deleteDuplicatesUsingIds(tablenum(Dimensions), 1, fieldset);

    // re-enable index
    ReleaseUpdateDB::indexAllowNoDup(dictIndex);

    info('Done');
}

D365FO: Entity cannot be deleted while dependent Entities for a processing group exist. Delete dependent Entities for a processing group and try again.

Scenario: There are times when you want to delete an entity from target entity list and when you do so, you face an error message which does not tell you where exactly the entity has been used.  "Entity cannot be deleted while dependent Entities for the processing group exist. Delete dependent Entities for a processing group and try again. " Solution: Browse the environment by appending this part  /?mi=SysTableBrowser&TableName=DMFDefinitionGroupEntity&cmp=USMF   at the end.  For example; if the environment URL is  https://daxture.sandbox.operations.dynamics.com then the complete URL will be https://daxture.sandbox.operations.dynamics.com/?mi=SysTableBrowser&TableName=DMFDefinitionGroupEntity&cmp=USMF Filter for Entity and it will give you the DefinitionGroup where the entity has been added or used in data management import/export projects.
