Partition Scheme

Hi, I have a large FACT-tables in my DWH (copy from a view in stage). I have tried to add partitions. I didn't help that much, so I removed it again.But since I removed it, the table can't be deployed. I get the below error. I can re-add the partition, but still the same error: An error occurred during drop partition function. See exception details for the failing objectAn error occurred during drop user defined function. See exception details for the failing object: Drop failed for PartitionFunction 'FactSalesOrder_History_PartitionFunction'.An exception occurred while executing a Transact-SQL statement or batch.Partition function 'FactSalesOrder_History_PartitionFunction' is being used by one or more partition schemes.

_L and _M Table Behavior

I am using the Field Validation to test our ETL. Using this as source data:And these rules in the DSA:And this query to check for errors:I get the following result:The _L table is linking to the records in the _R table that were removed when they failed the validation step on FIRST_NAME. Also the Warning level notification is not present in the table.As it stands the _L, _R, and _M tables as joined above are showing incorrect or at least confusing information. Am I using them as they were intended to be used, and has anyone done anything to get around this?Thanks,Mark

Working with Table Inserts

I have a table with fields defined (call it Table B), but no mapping.  I am inserting into this by using Table Insert (from Table A).  Think Table A -> inserted into -> Table B.  In the picture below Table A is Projects from D365 at the bottom of the picture.  Table B is everything else in the image.   DataAreaId is a field defined on Table B and is populated successfully from the table insert.  I would like to have a field, Field C, that simply does a custom transformation which places the value of DataAreaID into Field C.  While the Table B is fully deployed and executed, I am finding that Field C is unpopulated.  In fact all fields in the image that take values not from the Table Insert directly are unpopulated meaning I also can't assign constants.    So, all of the DimensionDisplayValue - xxxx fields in the picture are empty after executing.  I have also noticed to my surprise that the raw table is empty.  Not sure if this is by design or if something on Table B can be recon

Add related records, no relation between tables

I am unable to use the Add related records on a table. I get the error message "There is no relation between table-A and the table table-B". I have added a condition where the key in both tables should be equal. I have also tried creating a relation between the two tables in both directions but no luck. There is no mention in the docs that it is needed to add a relation before adding related records. I am getting a Warning that the source table is executed after the destination table. What am I doing wrong?

Default column value for simple tables in BU / ODX Server

Is there an option to set a default value for a simple table such that we can fill it with some value without doing any transformations. It then also should be possible to add fields for simple tables, but that you can only fill it with a default value. It would also be helpful in the DSA.

Invalid column name when transfer from uneven sources

Hi all, I have not been able to find any similar posts. My problem is that I stumble over an execution error when trying to map two different sources with identical columns, except one, that only exist in one source. I except data from one of the sources into the column and expect Null from the other on the lines originating from the other. But however Timextender throws error "Invalid column name 'XXXXX' " on the column at execution. Have tried full deploy. Only if I remove the XXXXX column it will execute. Any ideas?

_L and _M Behavior for Field Validations

Hi all,I'll try to find out how to get rows in the _L table when I use a field validation. For field validation I can decide if I get a warning or an error information. But I only get a message in the _M like this:How can I get the rows that don't match the field validation criterion to get an entry in the _L table?

Incremental Table insert - Is it possible?

Hi,I'm searching for a way to get a table insert incremental. I have a table (about 30 million records). This has a row for each hour of the day for 10.000 machines, so this table is getting bigger very quickly.I do a lot of transformations in this table. This resulted in a load time of over 10 hours. I've discussed this with our TimeXtender Solution Specialist and we've decided to split the table into multiple smaller tables. Now I do have 1 table (loaded incrementally from ODX), this table has a lot of lookups and simple transformations. This table is loading quickly because it's incrementally loaded.The result of this table is inserted in a new table (Raw table), using a table insert. This table is converting cumulative numbers to noncumulative, using the SQL functions LAG, OVER, PARTITION BY and ORDER BY. Because it is a table insert I have no idea how to do this incremental. I've set NonClusted Indexes (also on Raw table) on all fields used in the PARTION BY function. And enabled

Sorting a Hierarchy differently

I'm trying to create a hierarchy of GL accounts and the category they belong to. (i.e. Assets, Liabilities, Equity, Income Expenses).However the Hierarchy is displaying alphabetically.  If it were to be sorted by the first GL account it's associated with, it would sort correctly since GL accounts are numbered in the proper sequence.However, when I tell the Dimension, "Parent Category" (which is the Assets, Liabilities etc) to sort by Attribute Key, when I deploy I get an error saying it can't be used as an attribute because it is not related.Is there a workaround to this?

Conditional Lookup multiple values

I have the following set of tables: A (key1, key2) B (key2, key3) In that case, every key1 can have multiple key2 attributes in table A and every key2 can have multiple key3 attribues in table B. When I would use a conditional lookup field for table A to get key3, it would only give me one of the key3 attribues, is it possible to take all values? I know I could do it with a simple custom view left joining on key2, but is there are recommended way to do it in Discovery Hub without custom views? So the goal table should be like C (key1, key2, key3)

Using Collate on Join conditions

I am joining 2 tables T1 and T2 based on a condition T1.A = T2.BT1.A have values like 'wNFq' and T2.B have values like 'WNFQ', 'wnfQ', 'WnFq', 'wNFq'For a regular join a particular row of 'wNFq' from T1 gets joined with all values: 'WNFQ', 'wnfQ','WnFq' and 'wNFq' of T2My intention is to join only 'wNFq' from T1 to 'wNFq'.I achieved the same using custom SQL insert and using the below  COLLATE function to join based on case sensitive sequencing using:T1.A COLLATE Latin1_General_CS_AS_KS_WS = T2.B COLLATE Latin_1_General_CS_AS_KS_WSWandering if there is a different way to achieve this avoiding custom SQL.Appreciate any help on the same.

Filtering on the Look up fields

Created a conditional lookup based on following : T1 joined to T2 where T1.A = T2.B Looked up T2.C based on the above join condition and stored the value in T1.D Now I need to filter the resultant data set which is on T1 based on certain values of T1.D Unable to put that filter in the Table Data Selection Rule. Even I tried to copy T1.D(look up filed) to T1.E (a separate filed created just to hold the value of T1.D) and filter on T1.E, even that did not work. Appreciate help on the same.

database diagram: visualize your data model

Hi, i've setup a MDW layer with proper relations between tables. At this point I wanted to create a relation diagriam to visualise to my client the relation between his entities. my tool of choice was SQL Management Studio. Only then i've realised that TimeXtender only create DW_Id as physical primary key and the relations between tables are managed internally Is there a way in TimeXtender to visualize the relations between the tables? I've already put my vote here
